If you open a photo in, say, Microsoft Photo Editor (NOT paint tho, won't work), you can select an area of the photo, copy it, go to your database and paste it in a text item....

Now, there are lots of clippers (desktop image clippers) that could take a picture of your thumbnail in explorer, keep it as a .jpg, then to the trick above....
(A desktop image clipper is a program that let you select an area of your dekstop and clip it, instead of the Prt Scr that takes an image of the whole desktop)

VoilÃ*.

Just an idea.
