Illinoisbow: To doodle you have to open the picture with some sort of photosoft ware and use the tools available in the software. I have a couple different ones I use. You can also just use "Paint" in your "Accessories". The more sophisticated the software, the more you can do, of course the more it cost too. I like Microsoft Digital Image Pro 9 that I have. THere are better and there are worse. Depends what you want to do. I have just begun to crack the surface of all the possibilities. The simple stuff they're doing here can be done with Paint and it free if you have Windows. Just right click the picture and select Open with and then Paint. The tools are on the left and bottom. Make a copy of a picture and alter the copy and not your original because with paint when you do it and save it... it's there.
