Welcome to PT, engsohere! Your cat is gorgeous! I love that short thick fur, and the color too.

The picture most members have in the left side by their user name, is called an avatar. That has a limit of 60x60 pixels. If you can make it that size, it'll be accepted. If you can't, you're welcome to post the picture you want as an avatar and I'll resize for you. Or if it's one of the above, let me know which.
