[Mister X]

You can try looking at the source to see if there's a program listed. Most apps will add that into the head of the document. As a general rule I doubt that the galleries you saw we're made with a thumb program. Most likely it was handmade in Dreamweaver or some other similar app. That's what I use. I can create a gallery from scratch in an hour or less if it's the first one like it I've done. Using a previous gallery for a template and search/replace functions I can bang one out in about 10 mins. Programs like thumbsplus and arles are geared more to the personal webpage or paysite type of gallery. They don't give you the flexibility you need for something really kickass.
