I have made 2853 Artrage paintings, some very simple (some animations include Artrage paintings/drawings, I did not count these) some finished, some more sketchy. I probably have made more actually, if I count all the ones I have got tired of and thrown away.
On my hard drive I have about 3500 ptg files, including the ones I made for animations.

Now, I like to make a “photo book” of my ptg files. So I convert all of them to jpg in a blink, using XnConvert. It is a very simple to use program, very reliable and very free.

I mark the folder that includes the files to convert and make a new folder for the converted. The jpg quality is of course set to maximum. Start Converting! A minute or two later all the files are converted into the new file format for me to start designing my new Artrage illustrations book.
