We've used Virtual Gallery for years and except for a few software glitches, find it a valuable tool. We sell a wide variety of limited editions and VG gives us quick reference for that customer looking for a "Landry flower market print."
I suggest a computer with at least 32 MB of Ram to handle the graphics efficiently.
One added feature is that it entertains waiting husbands and children while mom does the designing. Even the computer illiterate can figure out how to use it.
If you are a limited edition dealer, you may want this machine to be internet connected. Eventually, all publishers will have detailed web sites that both you and your customers can access to determine price, availability, edition sizes, etc. This will be a pivotal sales tool, saving us all time and aggravation.
