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

[DivaVocals]

So sorry if this has been addressed, but I've searched and cannot find the answer. I've been trying to work my way through errors for 3 days now and have progressed to the point where I can't figure it out any more:

I have ZC 1.5.4
This was a new install.
I've installed the Tableau template. It came with the Image Handler 4 built into it.
I installed ZC from the automated script, and had to adjust a few settings to get the "all green" before installing.
Using PHP 5.2.17
MySQL 5.1.69
When I installed the Tableau template I got a few errors related to the install but managed to apply a few changes as per other threads and it installed.

My problem was that I wasn't getting images watermarking properly. After 2 days of diagnosing, I finally downloaded the latest Image Handler 4 and ran the script. I got the following errors:

Image Handler files all exist in correct positions in the directory structure.

Error The auto-loader YOURADMIN/includes/auto_loaders/config.image_handler.php has not been deleted. For Image Handler to work you must delete this file manually.
Success Image Handler has been successfully installed 

So after thread searching, I did a file compare and overwrote the files manually, and replaced the other files that were not created into the proper directory and deleted the script.

Now, images are watermarking properly. Very nice. Just as I want.

But now this problem:

My product images are not displaying the pop ups. And additional images aren't displaying properly.

I did some file comparisons and cannot find where things are going wrong.

Here's a link to a product page:

http://sunshinelocksmith.com/key-cat...&products_id=1

Notice when you click on the main image it says "The requested content cannot be loaded. Please try again later".

And when you click the 2nd image, the main image is blank.

I cleared out all caches and cannot trace where this might be giving me problems from. Nothing in the error logs to help either.

Not sure that this is aused by Image Handler.. Likely caused by whatever other image module you have installed or that came bundled with Tableau..

Personally I wish template authors would NOT bundle in things like lightboxes and Image Handler in with their templates.. they are GOTCHAS waiting to happen IMHO..
