yo, help

is there a way i can change photoshop/imageready archives into PNG, GIF, etc?oh and by the way, im asking this because im trying to make a sig (the one im using is borrowed)

If you have a .psd(file from Photoshop) you go into Photoshop and save it for web. You could always put the actual image into Photoshop then save it as whatever you want...
