Smaller pictures

I noticed that some of my coin pictures I uploaded, the thumbnail pictures are smaller than others.  Any ideas why?  I am at 300 x the size with no background.

An example:

If you list the coins from the country this one's thumbnail shows up smaller.

Because they are not properly cropped. See the screenshot of their copy in an imaging application:


I'll crop them and try to upload.

Done, pending verification. I marked pictures as "Took pictures myself" but added original poster's name into the copyright field - ken6528.

Just noticed that.

What you should do is say "Keep the source unchanged" so that way it doesn't link to your account, but Ken's. Also hopefully you're using PhotoScape to fix that big white background.

Ah, I see. I didn't do that. Should I re-do it?

No, but I use another program that I'm more familiar with (PaintShop Pro).

Anyone know how to do it in Photoshop Elements 4.0
