If you upload something straight onto PC, it'll become a GIF regardless of its filetype. If you upload something onto Tinypic or w/e first and then link it to PC as your avvie or profile pic, it'll become a GIF, but it won't lose the quality. If you do the same but link it as an image on your signature, it'll keep its filetype and quality. /like anyone's gonna listen anyhow
Back to sig. rating!
7/10
I think the text would look better if right-aligned so the ends line up perfectly with the image, and I also took off because the sig. causes the blog, quote, multiquote, and quick reply buttons to move to the left of it.
