ok, I hope someone can help me. I am trying to get a group end of the year picture of my class of kids. Well, there has always been someone sick. I got a great shot today of everyone but one and in my Print Shop 23 I added the boy and have a great photo. but...... it only saves in their software extension (.sig) or .PDF. I can not get these to upload to Walgreens and I even called there and they said no, it would not work. I really don't want to print at my house -- I don't think my printer has the best quality. Is there a free photo editing software program that you recommend? That would then save as a jpg? Thanks for any advice!
