I was wondering not really for a picture but for my signature pictures how can you edit the edges of the shots and make them like curve and stuff. I want mine to look better than just a box.

Ive seen a few people here on simv have some like that...

Thanks 

If you are trying to achieve something similar to below then i gotta know what software you are using. because i used CS4 for mine.

Dang what is it with you people and that Photoshop 7.0 stuff

anyways i know you won't get the full effect but try this
create rounded rectangle for the base. i can be rounded to what you want
then add the picture that you want on a new layer but on top of the rounded rectangle.
now here's the part that i'm not to sure that you can do; right click and select "Create Clipping Mask" this will round out the edges for the document regardless of what layer it is on. if you create a new layer above the others then be sure to repeat the clipping part
I know that Elements is kinda restricted in what you can do but other than that i don't know squat about it
