Hey Armor, i make sigs my self but im pretty fail at them here is what im working on.
Problem is the lowest i can get the quality is like 51kb without sacrificing alot of image quality, i dont know what to do any suggestions pm me if it is more convenient for you. By the way i dig your sigs.
That sig is pretty nice! Don't down on yourself for that.
As for the quality, that's one of the hardest things about sig creating for TechPB. Getting it below 50KB is sometimes really difficult. Instead of working with an image 600x150, try working with one that is 500x100. You would be amazed how much smaller it is. I usually don't make signatures bigger than 500x150, because of that limit.
Sometimes, if you save it as a different file type, then it will compress. If you are using .jpg, use .png. Give that a shot. (or it could be the opposite...)
Try those and see if they work. Oh and bytheway, what software do you use? GIMP or PS?
