You can recall an image from a DropDown List in the same way you recall a document, but keep the following in mind.

 If you just want to recall by name (without extension) the path to the folder much contain the word 'picture', 'image' or 'photo'. (The plural is okay; caps do not matter. It can be the immediate parent or a grandparent path).

 If the image is not in a folder containing any of the above words, Pathagoras can still find it, but you must contain the correct suffix (.'jpg or .jpeg. .gif or .tiff or .bmp) name.
