ebay photo size problem

[fohat.digs]

I have not sold on ebay for a while, but now I want to clear out some excess stuff.

My listing keeps getting rejected because the "picture size is too small" and asks for a minimum of 500 pixels on the long side.

But my photos are around 2K on each side, well above their requirement.

What's the deal?

Strange, I know that this minimum of 500px is there, which sometimes pisses me off, but never had problems that huge photo didn't work.
You can do what I always do - open up required photo on full screen, make screeenshot and then save as big size.
Weird...
