Product Image PopUp _LRG Setup

Good day to all,

After searching everywhere. On a product image, I have tried unsuccessfully to configure my thumbnail product to: when clicked on to show the _LRG 400 pixel wide large size, in the pop up window. I can get it to work with an additional set of extra thumbnails that shows up below the product text, but I am looking for a setup as follows: http://www.brewershirts.com/black_market/index.php?main_page=product_info&cPath=1&products_id=15

I have followed all threads.

I have a custom template called skaterschoice.
Under images directory I have skaterschoicesmall, skaterschoicemedium, and skaterschoicelarge. I have tried all the below using the medium and large sub directories also.

All images are setup like instructed.

I use admin to upload the small thumbnail 100x "j109m_01.jpg"
I then use filezilla to ftp to respective folders on server, reset all to 777.
I have also tried to load via Admin the "j109m_01_LRG.jpg" first then second upload the file "j109m_01_MED.jpg" and finally the the small thumbnail "j109m_01.jpg"

I have tired different check boxes in Admin with all combination's the Overwrite Existing Image on Server, etc. I have tried all combination's even just Uploading to Main Directory = images, no success. I have also tried various combination of uploading the 2 additional sizes to the original Images/Large and Medium sub directories under images, and no success.

I have made sure to delete the images on server before each attempt.

I have cleaned out my cache in Firefox and IE.

Do I need to add info in the attributes, I have added _MED and _LRG with no success. Do I need to edit the css stylesheet?

I can upload the "j109m_01_LRG.jpg" via admin and have it populate the site and work like in the example above but I am concerned that if I go this route the image file size will slow down the page when I have 30 plus thumbnail images on a particular page. (that are really the _LRG versions) I am running around 40k _LRG and 20k small thumbnail images.

What am I missing. I am sure it is User Interface or a Short Between the Floor and the Keyboard. :smile:

Thanks for you assistance

The Old Guy.
