For something like that, where you (I assume?) created the image in MS Paint or something similar, the source would be "User-made". That's all that's required for an image you personally make using no other images.
 * Here is an example of one of mine; I made it entirely in Corel PaintShop Pro X5 without incorporating any external images, so the only Source is "User-made".
 * Contrast that against this one; I made that mostly on my own in PaintShop, but I found the stock image of a flame online and cited it accordingly. "User-made" is still the main listing for "Source", because I did most of the work on the image, but I still cited the incorporated stock.
