Image Handler 4 (for v1.5.x) Support Thread

[DivaVocals]

Not true.. the IMAGE HOVER feature of Image Handler doesn't work on the medium images displayed on the product information page.. Otherwise image Handler manages ALL product and category images..

If understand correctly, in places that are normally a medium image, are wondering why IH4 doesn't override that. For that, read the instructions. Medium images are not handled by IH. I forget the explanation why, but if you want a different image to be displayed so that it is handled by IH then would need to change the ZC code to display a different sized image in place of the medium image.

Tells me that you uploaded your main product image (the "medium image") to a folder called "/images/medium/Jenny/": http://leather-jackets-leather-fashion.com/images/medium/Jenny/002_MED.jpg. Your other images on the other hand are located in a folder called "/images/Jenny/": http://leather-jackets-leather-fashion.com/images/Jenny/002_01.jpg.

Your medium image gives one a 403 error (which is why it doesn't display). 403 error aside, the first thing that stands out for me is that there is NO REASON for you to put images in the "medium" or "large" image folders, nor is there any reason to name your files as you have done with the "_MED" appended to the file name. In fact you should NOT use these folders or naming conventions at all..

As stated frequently in this support thread and in the IH4 readme instructions, you DO NOT (SHOULD NOT) need to upload specific small, medium, or large images at all.. You do not need to upload images to the "medium" or "large" image folders, nor do you need to append "_MED" or "_LRG" ro your file names.. Upload your LARGEST IMAGE and IH4 will generate optimized small, medium, and large images for you. So I would start with removing the images in the "/images/medium/Jenny/" folder and edit the product to make sure the largest main product image is in the "/images/Jenny/" folder.

Secondly because of the way ZEN CART magaes additional images, you are going to need to change your image names from what I assume is the default manufacturers image names. Your images names should NOT contain ANY numbers otherwise you will find that eventually images that belong to one product will appear on other products as well..

Hi,

Can someone put me in the right direction here, as my main images are not showing in zen-cart-v1.5.1-full-fileset-09182012

I was using Image Handler 4 for v1.5.x - Version: v4.3.1, but it did not show the images in the IH manager in admin (see post above - and included screen shots), so I did a complete uninstall of IH4.3.1 (used the IH built in uninstaller from ZC_admin), and deleted all the files that IH left behind (checked against the original IH file structure), also deleted the bmz_cache folder.

As it is suggested in your image_handler_readme.html, zen_lightbox needs to be installed (or some files to be re-written) after IH installation.

Therefore I uninstalled zen_lightbox-v1.6.4_1, by manually deleting all the files and running the uninstall.sql to make sure that nothing remainde of both IH and zen_lightbox installations.

Following your install instructions, I did reinstall Image Handler 4 for v1.5.x - Version: v4.3.2. In ZC_admin the installation went ok (all green messages).

Then I proceeded with the installation of zen_lightbox-v1.6.4_1

Here is the URL of a test product:
http://leather-jackets-leather-fashi...t-002-p-9.html

Looking at the DOM source of the page, I am puzzled by looking at the directories that the images are located in:

• productMainImage: <img src="images/medium/FOLDER_NAME/002_MED.jpg".........../>
• productAdditionalImages: <img src="images/FOLDER_NAME/002_01.jpg"........./>

Here is part of the DOM source code:

<!--bof Main Product Image -->
<div id="productMainImage" class="centeredContent back">
  <script language="javascript" type="text/javascript">

So please can you tell me what went wrong, and why I have 2 different URL's showing?

Many thanks for your help,

I stand corrected. I obviously did a less than thorough review of the situation. Keep up the good work.

Hi Everyone...

I seem to be having an issue. I have installed the Image Handler 4 and I am now getting Page Not Found when I ad product to cart. Any ideas? I believe I installed everything correctly as I have installed this thing about million times before on other sites, but there seems to be a problem here, not sure what needs to be checked. Thanks.

I have run across this in only one situation, it had to do with the dimensions of the image. On my site I have to have the maximum dimension in either height or width less than 1024. When I had run across this, if I added the picture I would get a page not found response in admin. If the image appeared on the main page, I would receive the same. If the image was not on either of those, then things would work, but as soon as I selected an option that was to display the image, then it would fail out again and I would have to back up to a previously functional screen.

Ultimately I think I had to go into mySQLadmin and remove the picture reference so that things would function again. Then I downsized the picture(s) and uploaded again without issue.

Well...my images are set to 150x150, 400x400, and 550x550. I don't seem to be having any issues in the back end of this, just the front. When I add product to cart, it takes me to the page not found.

I did go through my FTP and saw that it had files missing from the install, so I loaded them and am still having the same issue. Not sure what to do now.

and what makes you think that this is an issue cause by IH4?? IH4 would NOT affect the shopping cart behavior you describe (otherwise many others would report the SAME issue).. What other modules have you installed?? If you roll back your install to a pre-IH4 state do you still have the same problem??

Also a link to your site would be quite helpful.. (as suggested on page 1 of this support thread and in the readme file..)

Tips for posting IH4 support requests..

BEFORE YOU POST A SUPPORT QUESTION HERE READ THROUGH THIS SECTION (this is from the Image Handler readme file):

Troubleshooting Basics
Make sure your custom template is active. (Admin > Tools > Template Selection)

Make sure Image Handler 4 is installed. Admin > Tools > Image Handler4 > Admin Tools. Set permissions in both your images and bmz_cache folders to 755 (eg: both of these folders need to have the same permissions).

If Image Handler 4 does not work or gives you errors:

• Make sure all files are in correct location
• Make sure you uploaded ALL the Image Handler 4 files
• Make sure the files are not corrupt from bad FTP transfers
• Make sure your file merge edits are correct
• MAKE SURE YOU RE-READ THE CONFIGURATION AND USAGE SECTIONS!!!
• Make sure that there are no javascript conflicts from other programs
• Make sure that your main product image files names DO NOT contain any special characters
  ie: non-alphanumeric characters such as
  / \ : ! @ # $ % ^ < > , [ ] { } & * ( ) + =
  
  Always use proper filenaming practices when naming your images - See this document as a reference: http://www.records.ncdcr.gov/erecords/filenaming_20080508_final.pdf\

When posting bugs/issues about Image Handler 4, it's a WHOLE LOT more helpful to resolve them if you post details. Just saying "it's broken" or "doesn't work" does not provide nearly enough information to help YOU resolve YOUR issue.

Please provide as MUCH information as possible including:

• The version of Zen Cart you are running
• The version of Image Handler 4 you are running (you can see this by going to “Admin > Tools > Image Handler4” – the version is displayed in the upper left hand side)
• Any other add-ons you may have also installed
• Hosting/server information (PHP versions, mySQL versions, hosting provider etc)
• The EXACT error/issue you are experiencing
• AND if you're REALLY detail oriented, tell us the install sequence/method you used to install Image Handler 4.
• Post a link (not a screen print) to a specific product/product listing page where the issue you are experiencing can be seen (Please DO NOT make folks fish through your site looking for an example of your issue)
  
  AND this last point is important.. The volunteers who help here need to SEE what you see LIVE. A screenprint really isn’t good enough.

And a (gentle) reminder about FREE forum support:
This is ain’t Microsoft folks!
(a frequently used analogy by some to compare open source projects to commercial projects)

Like other open source projects, this support forum is manned by VOLUNTEERS (ie: unpaid folks). They are not OBLIGATED to assist here, but they do so because they WANT to. They give of their time here when their individual schedules permit. Usually the response is pretty quick 'round these parts, but when it’s not or your question has gone unanswered this may mean one of a few things:

• NO ONE has an answer to your question/issue.
  (Some folks will only respond when they have something MEANINGFUL to say versus a blanket “I don’t know how to do that” kind of answer.)
• Folks are just busy and will answer if/when they can..
  (family and other personal obligations, day jobs, paid jobs, etc will usually trump forum participation – this is to be expected – after all it’s unrealistic to expect that folks are sitting around this forum all day and night waiting to answer questions)
• Your question got missed. (and while I’m on this point) Your post MIGHT have been missed if your post is now a FEW pages back (like more than TWO or more pages) with no response.. Missed does NOT mean “it’s been an hour and no one responded to my question, so let me 'bump' the thread by re-posting my question again”

Anyway.. carry on.. Enjoy the new version..

Well...I didn't think so either. I am working on a site for a girl and I cleaned up her layout (no installs) and installed the image handler for her. When I left I didn't see any issues and everything seemed to be working beautifully although I didn't try adding any items to the cart so I am not sure what happened between the time I did the install and this morning. I will wait to hear from her and get back to you with more details...or another thread somewhere. LOL. Sorry...but thanks for your help.

[amandavz]

Okay...I see that she also cannot receive message from her store either. There are no files in Image Handler that would cause this is there? Just double checking so that I can get this pinned down. Thanks for all your help.

No.. otherwise others would report the issue.. but based on the files IH4 modifies, and the function it provides, there would be no logical reason to conclude that IH4 is the cause of the issue you describe.. I suggest you roll back the store to where it was before you installed IH4, and resolve the checkout issues.. My guess is that some other edits you've done are the source of the issue or it was an issue that PRE-EXISTED before your made your changes..
