I downloaded ImageHound. What a cool idea- like the Find Image app that used to be built into Macs around 6 years ago. I thought it would be a good addition to a graphics toolbox. I LOVE GraphicConverter (Lemke Software) which also costs $30.
When I diddled with ImageHound, it worked once but I could never get it to work again with a second search. I guessed that it was crippled software, usually called "shareware". Thus I went online and paid for a licensed copy ($29.95).
I reopened ImageHound. It crashed. I reopened it and worked through the instruction manual (too thin and written condescendingly). Still could not get the app to do anything it claims to be able to do. What a COMPLETE WASTE OF MONEY. Aviod it at all costs!
