If you host images on eBay, you won't have to decide what size to display your
image. eBay resizes all images to display at a resolution of 400 X 300 initially.
On the other hand, if you, like most serious sellers, host your images outside
eBay, creating a convenient, attractive auction layout starts with image size.
The most important point to remember is this. No matter what screen resolution
you have your system set to, about one half the people who view your auction
will see something entirely different than you.
The purpose of this tool is to let you see, to an extent possible,
how possible buyers will see your auction pictures at different screen settings.
To use the tool, simply paste the URL of an auction image in the field above
and select a screen setting.
