Also there is a JavaScript method to pull any image you want with any dimensions:
Make a call to json.mvc with the following parameters:
Session_Type=runtime Function=Runtime_ProductImageList_Load_Product_Var iant Product_Code= Variant_ID= Image_Sizes=pipe separated lists of dimensions, either the string “original” or WIDTHxHEIGHT
The output will be a JSON array containing URLs to the generated product images.
You would then read in the JSON and update the page accordingly.
