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

[weif]

I checked out the page you linked to, and that product page is not using image handler to resize the image - the image on the page is still the image in the images directory - and it is quite large. The same is true on your product list pages.

The zoom function works for me, but the page that comes up shows the image at 150x75 because the image tag has that width and height set for the image.

Did you look through the "help" information on the ImageHandler4 admin page under the tools menu in your admin? This may have some helpful information. I suspect that some file (or files) on the public pages isn't installed correctly.

Thank you for the reply.
I have overwritten the source files from the zip several times now.

"that product page is not using image handler to resize the image"
...hence my post


"function works for me, but the page that comes up shows the image at 150x75"
...yes, the popup pops up, but no larger than the small image, hence my post.

"because the image tag has that width and height set for the image."
...is that why it is small even when 'enlarged'? If it is that simple, where should I set the image size so that just the enlargement is large?

"Did you look through the "help" information on the ImageHandler4 admin page"
.,..yes, it says "You can simply upload just one large image (that gets resized as required) or you can have different sources for medium and large images."

..which "simply upload just one large image" is what has been done.
This has never been a problem before. It wasn't a problem with 1.3.9, it wasn't a problem on my local wamp server.

Thanks for the suggestions.

Yes, it should be that simple, and it was on my 1.5.1 installs. If it is working on your local WAMP machine, but not on your (I'm guessing) WAMP web server, have you diff'ed the product files to see if you can see a difference there? Are you using the same template on both servers?


Another thing I noticed there is that you are giving us full paths on your local drive (file:///C:\) when you refer to what is shown on the image handler admin. Those files aren't accessible to web users - at least not at that address. This particular piece of information would appear to be taken from a copy of Zen-Cart running locally, not on a web server. Can you confirm this?

Image Handler for the above product reports as follows.

Image name	File Type	Default size	Medium size	Large size	Action
1736 roses & plumes shilling 001	.JPG	[IMG]file:///C:\Users\Sup\AppData\Local\Temp\msohtml1\01\clip_image001.jpg[/IMG] 142x75 3.56Kb	[IMG]file:///C:\Users\Sup\AppData\Local\Temp\msohtml1\01\clip_image002.jpg[/IMG] 227x120 7.56Kb	[IMG]file:///C:\Users\Sup\AppData\Local\Temp\msohtml1\01\clip_image003.jpg[/IMG] 750x395 55.41Kb

I am quite stuck now, since IH4 seems to be installed, but not communicating with the default Zen Cart files.
I have looked through the forum, but cannot find a relevant post, since I am not getting an error message as such.

Since we cannot see your site, it's hard for any of us to say what might be going on on your site.. I will make a few observations though..

• Your "File Type" is uppercase... Do any of your images have lowercase suffixes?? JPG and jpg are treated differently by Unix servers.. You should change them all to lowercase and modify the suffix settings in IH4 accordingly if this is inconsistent.
• All of your filenames are not what I would consider good/proper/best practice naming conventions for your image file names, and for use in Zen Cart in particular.
  
  • The numbers in some of your image names can be problematic with the method Zen Cart uses to identify additional images as they could mistakenly be associated with the incorrect product.
  • For example this image name "1736 roses & plumes shilling 001.JPG" might be better as "roses-n-plumes-shilling-001.jpg". Please note the removal of the ampersand (character used in programming), the elimination of spaces (different servers handle spaces differently.. not always consistently), and the use of a lowercase suffix (more common naming convention practice)
  
  

The suggestions above may not solve the issues, but they are practices you should be using anyway as they will prevent other potential issues which may impact IH4.

Suggest trying some other things to boot..

• Eliminate your template as a root cause.. Some template authors make hard coded changes which impact other modules performance. Switch to the Classic template.. Re-install IH4 so that it get's installed in the Classic template folders. Does the problem persist??
• Check with your host to make sure your GD binaries are installed correctly and working..
• Double and triple check your install to make sure you copied over EVERYTHING (yes we know you checked/reinstalled/etc.. humor me and check again please..)
• Try uploading a completely DIFFERENT image. Not one of your product images.. Download the Zen Cart logo from this site.. Upload it.. Does the problem persist?? If it doesn't the issue could be a number of things including the size of your images, or even some kind of file corruption with your image files..
• Are the files you are uploading in the file format you are specifying?? IH4 has a built in image converter which will for example allow you to upload a JPG and have IH4 convert it to a PNG.. If you are using this feature to upload say a BMP file, its POSSIBLE that the conversion corrupted the file..

If none of this gets things back in order, one last thing you can try is doing a CLEAN vanilla Zen Cart install without your data, apply your template, then install IH4.. Test and make sure it's working.. If it is, then export your DB and import/restore it into your vanilla store and test again to see if things STILL work..

After all of this, if all else fails, you may have to consider paying someone to take a look and troubleshoot this for you..

One curious feature is that the file header_php_IH4.php in
/public_html/includes/modules/pages/popup_image_additional
renames to: header_php.phpIH_1419950695.OLD.IH4
which I do not understand.

As explained in the readme:

• Files with the ##########.OLD.IH4 suffice are your original files which IH4 renames and saves as a backup (once things are running smoothly you may safely delete this file)
• Files with the IH4 suffix are the IH4 installer files. They replace an equivalent file (usually an override file) of the same name with the PHP suffix instead of the IH4 suffix. (once things are running smoothly you may safely delete this file)

Thank you for the reply.

I think that was a copy/paste mistake.. I believe kevin was trying to copy images into his post..

Thank you for all the suggestions.
The fact is I would prefer to not want to need IH4.
I resorted to it when the enlarge function on the site was failing, so I thought to fix it with IH4.
Silly me.

It seems zencart works to enlarge images in its native state anyway, as it always did. That’s all I want.

I have made a fresh 1.5.3 install into a subdirectory on the server, created a product, and the enlargement works perfectly well…here..

Since that is all I want to do, it seems IH4 is superfluous.

However, this new install is now proving difficult to import my backup up database into.
Why oh why is ZenCart so tortuous?

I now have the front end public area with faulty functioning,
and a subfolder copy of zencart which I cannot dump a database into.

Let me see..which nightmare shall I follow?

Sorry, but I am sick of this software. I have read endless threads of problems similar, and I really appreciate the efforts of kind users to help.
But I have now wasted days (I have read that so often in other posts)
and have turned a perfectly functioning site into a screwed up failed upgrade site.


Since I want to avoid IH4…(every add-on seems to bring another set of complications I which I can do without)….I shall divert to the subfolder 1.5.3 copy, and try to bring that to a point where it can be transferred to the root folder which means I need to start another thread in another section to solve the import database problem, and follow the journey along yet another branch of this pitiless maze.

Thanks for trying to help though.

Yes, that was the case the actual paths were

IH4 is hardly superfluous. It provides a rather useful purpose and that is to optimize images (thereby improving site performance) in addition it adds features which aid in facilitating the process of managing and uploading product images.. Now if you don't want these features, then that is a personal choice, but superfluous implies the module serves no useful purpose, and I wanted to clear that up..

That said it now sounds like you had a pre-existing issue with the image enlarge function. Sounds like you thought IH4 would fix this issue.. IH4 would NOT have fixed this as IH4 doesn't modify Zen Cart's native image management or the behavior of native functions.. (Doesn't modify the image enlargement function AT ALL) IH4 instead ADDS additional features which only work when the native functions are behaving as they should.

[kevin_a]

I did not mean to suggest that IH4 was globally superfluous, but that in my case it was, and perhaps should had added "to me", although I thought that was implied in
"Since that is all I want to do, it seems IH4 is superfluous."

Given your observations, it would indeed appear that the issue is higher up the structure, outside IH4, but I cant imagine where I would begin to look for that.:-), so decline to follow that branch.
With my fresh install of 1.5.3, I am now engaged with upgrading the database using buggy software which itself needs patching in files that dont even appear in my folders.
But that's another story.

Thanks again for prompt responses. All appreciated.

Image hover and resize issue:
ZC v1.5.4
IH v4.3.2
All install went through with no problems, image loaded with all the resize with no problems. But when trying to view it on the product page, the hover zoom doest not happen and clicking on the image does not bring up the large(original) image. Any suggestions is greatly appreciated.

This would appear to be a very common problem, I have searched and reviewed quite a few threads with this common issue but have not found any solution yet. I have verified the IH installation and each of the effected php files. I must be missing something.
