Transparent, Windows Regular and Enhanced MetaFile (WMF & EMF) images for your ffe drop window..
This is just a random sample of some of the most appropriate images I could find in my old clip-art archive. I have no idea who created these, though I'm fairly sure some of them are from standard Microsoft clip-art packs. If you have credits for any of these, please pass them along to me. Cheers! I have left the file names as-was, to help with this.
NOTE: the previews (below) are PNG files. If you want the WMF/EMF files, download from the links above.
