I am sure they are random sets of letters or even words that are in the database with links to the graphics that represent them. They could either be individual letters or even sets of letters. Thee are then randomly chosen. The customer enters what they see on the graphics and the result is compared against the db. It seems that simple to me. Yahoo already does this. I am not sure if this is the mechanism used, but it would be a good candidate. All you would need is the randomizer function to come up with a random number...or a series of random numbers and that would be what is pulled from the db.

Some kind of a "glyph" I thought, but my feeble attempts at the googling were too generic and produced way too many search hits. But I'M SURE that a few weeks (months?) ago I saw someone on this list make mention of some CF code for doing just this. Anyway, TIA for the answer!
