You get to the info box with Shift-I. Then you choose the second tab, which is called something like "creator info", sorry my version is in german and I'm just translating as I go along

Yes, I use PSP, create a small file and use every brush of a set once, save that file as jpg, call it the brush name and store it in AZZ cardfile and add all the infos about it I need. I love that program.
If you would like any more info about it, just let me know....
