I too have an issue with product thumbnail sizes. I have set the thumbnail images to 300 x 300 in the main >images area, the product size to 400 x 400 and the image size to 800 x 800 for the popup. My issue is that when the product list shows, the first 2 products show thumbnail sizes of 300px x 300px scaled to 71px x 71px. Even though the original sizes of the first 2 images are about the same, the second image shows 300px x 300px scaled to 90 x 90px. The third image shows 300 x 300 scaled to 142 x 142px. I have tried deleting all of the images and also all of the thumbnail images off the server, but as soon as I upload them again, they display the same. I don't understand where the scaling is coming from and if I have set some arbitrary field, why are they all displaying different scaling amounts. The URL for the development site is

. I would certainly appreciate some advice here.
