image sizing in the back end admin

Hi would somebody mind explaining which of the image settings in the admin relate to the medium images and which to the large images .. small image width is pretty self explanatory but Product Info is medium? or is it Image-Product Listing width? or Image - Product All Listing width? Thanks Using ver 1.3.8a

Hi would somebody mind explaining which of the image settings in the admin relate to the medium images and which to the large images .. small image width is pretty self explanatory

Product Info is medium? or is it Image-Product Listing width?
or Image - Product All Listing width?
If you view the frontend

ProductInfo is the product detail page and would me the medium
Productlisting is the page where several products are listed normally/default in row format

Note the "All" selection in the categories box - - this is the all listing

Um yes well .. which one is for the click here larger image? My medium image size is working when I update product - info listing but my larger image is still not displaying and I have updated image - product listing with the large image size. Thanks

It defaults to the actual image size and is not settable from the admin

So if you have an image my_image_LRG.jpg that is 1600X800 that is the size that will be displayed for a large image

Great, thanks for letting me know, was going through every setting.
