GIMP does drop shadows
Well, my “drop shadow” dilemma didn’t last long. I found a quick and easy feature of GIMP - my graphics editor or choice. GIMP is probably as complex and complete as Adobe Photoshop but GIMP is open source and free (and runs on many different Linux distributions, Windows, and Mac OS X).
GIMP has the drop shadow tool built in plus there is a large library of other scripts (aka macros aka plugins) available as well. So it is easy to support your favorite workflow for photo retouching, graphic arts, or other artistic expression.
The drop shadow feature is located under “Filters -> Light and Shadow -> Drop Shadow”. For my small pics, I use and offset of 6 and 6 with a radius of 8 and then choose a medium gray for the color (the default black was too harsh). The results work well for my desire.
