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

[DivaVocals]

I'm confused with the IH4 installation.

I did the auto install and I had no row headings in admin->images (those IH adds)...

So I'm back to backup and trying to figure out how to do manual install.

I have to rename and merge those files into the proper names/directories and then upload them - so this is manual install?

No.. and honestly you haven't posted enough information to tell us what might have gone wrong. (no link to your site, no error messages.. no indication as to whether or not the IH menu is available in the Tools menu, no idea what version of Zen Cart you are running..)

and I need to say this again.. IH has NEVER used external SQL scripts to add the entries in the configuration table to add the IH image configuration options .. It has ALWAYS had an installer that had to be run from the admin. The ONLY thing IH4's installer brings to the table is that you now no longer have to "click a button" to execute it..

I'm running 1.5.1

I installed following the 'auto' setup - only renamed the admin folder and uploaded.

I saw bunch of rows (all of them green) when the installer ran and then as follows in the instructions I went to Images to enable IH but there all IH field header names were blank. The settings were visible but...

Then I went into the 'admin' folder of IH and saw there's language versions I was not copied for my other 2 languages - I did that for BG and ES lang., uploaded them but no luck again (the same EN files, all my admin section is EN for all langs)

I didn't saw if IH menu was present in Tools, but the changed 'categories' file was working.

I reverted back to original state now. What I did wrong?

Hi Diva!

I have a new install ZC 1.51 + IH4. The module installed fine, and is creating cached images, and hover is working as expected.

I have a couple questions. I'm 'new' to Image Handler so I hope you don't mind.

1) Have you ever seen situations where IH4 has slowed down a site - meaning longer page load times? When I enable IH4 and refresh the page, I am getting a slight pause before the page renders. Settings are pretty much default with default zencart.

2) I'd like to use Magic Zoom from magictoolbox.com. Pretty nifty. Have you tested IH4 with magiczoom, or heard of any conflicts?

Thanks for the hard work!

IH4 ususally improves a site's performance.. So if you are experiencing some slowing I have to wonder if there isn't something else on your site that is causing it?? Post a link and we can give you a better idea..

You will not be able to use any kind of image zooming tool with the IH4 image hovering without some serious re-engineering of one or both tools to allow both to work together.. (it's on of the BIG reasons why zoom on the medium product image doesn't work in IH4)

Hi Diva (weif & nicol too!)

Thank you for the responses.

Yes, I figured first time loading a page would have a hit as the cache was created, and that is very obvious. It could be browser or even something in how apache is set.

I can confirm that magiczoom does not work perfectly out of the box with IH4. There seems to be some conflicts in variable name use and creation between the two modules. I keep getting an E_Error warning from PHP when the two are enabled together, but each run fine independently.

Unfortunately, magiczoom uses compiled javascript, so tracking down the conflict is made much more difficult.

Nice effects though!

Try a different module then.. niccol's suggestion:

i do know that jqzoom plays nice with IH and there is a thread in which i am beinb persuaded to turn some code snippets into a proper module. search and you will find it

Some files that IH modifies are core files. This means that IH overwrites the existing files that Zen uses. If your site has no modifications to these files then there are no problems. If your installation has existing modifications to you files then you will have to carefully merge the existing modifications with the modifications that IH makes. There are a number of ways of approaching this.

As always the best recommendation is to do this on a development version of your site. If you are serious about running your store it is always worth having a second version of the store so that you can experiment on that first. I know that this seems like a lot of work but it really is worth it and does not actually take that much time.

=======================

Route 1

This works for installations that have no modifications.

Just install IH and it will work. If your admin is in a language other than english then read this thread for instructions.
=======================

Route 2

This works well if you know that you have files to merge and is a good option if you don't know if you have merges to do.

Install as normal. The installer will create backups of any files it overwrites. So, just go for it. Then check your site. If everything is working well then you are good to go and you didn't need to do merges.

If problems have been created it probably means that you have merges to do. So, you can look on the server and find the backup versions of the files that have been created. Download the backup version (this will have your previous modifications). Download the active version ( this will have the IH modifications) . Merge these two files and upload the result as the active file.


=======================

Route 3

This is the way to go if you know that you have merges to do.

Read Diva's post above and see which IH files are equivilant to which Zen files. It is not a complex pattern! Then merge your modifications into the appropriate file in the IH installation files.

For instance if you have existing modifications in

/YOUR_ADMIN/includes/modules/category_product_listing.php

merge them with the installation file

/YOUR_ADMIN/includes/modules/category_product_listing_IH4.php

Then install as normal.

=======================

What happens during install is this:

• The files are uploaded to the 'wrong' place.
• A backup of your existing files is created
• Then your files are overwritten

The logic is based on the fact that less experienced users have been known to upload files and overwrite existing file modifications. And those modifications may or may not be correctly backed up. There is potentially no recovery from this. Creating a backup before overwrite means that recovery is possible. However, to allow files to be backed up the IH files cannot be uploaded into the 'right' place because that is potentially destructive. So, they are put in an alternate position and then moved into the right place once the backup has been created.

Hi Diva!
1) Have you ever seen situations where IH4 has slowed down a site - meaning longer page load times? When I enable IH4 and refresh the page, I am getting a slight pause before the page renders. Settings are pretty much default with default zencart.

In my experience, when you first load any given page after installing IH, it does have a slight delay while images for that page are created. However, once any given image has been created, the pages do load faster due to smaller image files being transferred.

You say you are using another language in your store.. Try making the change from this post: http://www.zen-cart.com/showthread.p...11#post1117911

I didn't saw if IH menu was present in Tools, but the changed 'categories' file was working.

Not sure what you mean by this last part.

Suggest making the change in the post I included (above) and then try the install again..

I have not been this confused for long time with ZenCart modules....

How do I have to merge the files - some of those files are missing (my template don't have them) some are different.

This time I copied English folder (no edits as suggested above!), renamed it to Spanish and Bulgarian and installation underwent well - I enabled it, it's working but I can't seem to figure out which rows have to go where when merging...

Do I have to add all missing rows from my original files to the ones IH made or what?

I'm really lost on this one...

Also - If It's going be easier to make manual install - what I have to do - add all aditional rows in _IH4.php files to the ones I already have and not upload _IH4.php files (only the rest) or what?

www.rampagehockey.eu/neo - currently it's not displaying product info image because the author made the template to load large image there - will modify this latter but now I have to merge those files so he can work upon that...
