Im too lazy to cut my own pics. I usually use a cut gallery or i just do a manipulation on the original picture. If you do it right you can make it look like the picture was a cut. Theres a few good cut gallerys out their though PSDCentral used to be a great site for cuts but the new site owner was terrible and the site died. .o2 Designz has a lot of good cuts. I am a mod over their and its a great site. Most of the people at PSDC went there and it has a cut gallery with a lot of cuts. Most of them were cut by the same people to. Surreal Designz has a few nice ones but doesnt have as many good sports cuts. sdsportsfanatic has a pretty good selection of nice cuts. SD is a cool guy and his site also has some nice tuts.
Didnt mean to spam or anything, just trying to help out.
