Hi All,
My Newbie observations are:
* Pictures are uploaded in the size that they are on your PC.
* Any Auctiva hosted pictures are resized to 400x300 in the listing with a message something like click here to supersize which seems to link to the original sized image.
Like you the 400x300 does not suit the fact that I upload images that have already been cropped and resized.
The fix for me, that I discovered accidentally, was to design my own listing template. In that you can choose whether to list the images at 400x300 or in their original size.
Hope this helps.
