X-Post! Girls who did their reviews! Do you know what sizes your pictures were?

I don't know whats a good size for a pic... on Photobucket i've been making them 320x240 (the 'medium' size.) Is this too small?

Before I put the TP Proof into the review, I want to make sure they're not too big, but not too small where you can't see how pretty they are!

TIA!
