Now that I’m in the process of doing the uploading, I can report that FineArtAmerica.com handles the uploading of files much easier than Imagekind does.
When I uploaded on Imagekind my browser froze (Mozilla on a Mac) and the same thing happened when I uploaded using Safari. In order for the browser problem to be corrected, I had to restart my computer. In a 3-hour period I was able to upload only one photo on Imagekind.
FineArtAmerica, however, uploaded my files quickly without causing problems with my browser. The site is easy to navigate and does a nice job of organizing and displaying my photos. Take a look at http://fineartamerica.com/profiles/matthew-bamberg.html.by
