I finished my first signature, now I want to share it, but its in a PSD file, whenever I open it, it goes into photoshop and loads the picture. now how do I upload this picture to photobucket to share? PLEASE HELP
i use photoshop cs4

Cant you save it as a jpeg? Also go to photobucket site. Make an account.
Are you that far yet?

no save it as png much better then jpeg

ok you save the file has png onto your computer then go to photobucket and go to upload and search for that file upload it then click on it on the list photobucket has then right click and click view image then copy the adress and paste it wherever u like
