I just downloaded paintnet. I feel like I was just born. I really need help. Is there a manual, or somewhere to go to understand it all. I would just like to make funny, pretty, and quircky pics. I saw somewhere that you have to download other things. Can someone give me an idea of what I need to do now? Also, how do I get my pics in the program? TOLD you I am very new, even to computers. I'm the old lady who wants to be a pro. Any help sure would be appreciated.
