After several days working on my site, I've arrived to a point were I feel more comfortable sharing it. It is still very much a work in progress, but I think it is usable enough to start being useful.
The whole refurbishing happened after I learned somewhere in the net that there was module for my gallery that made it shake hands with an e-commerce script. This is how it goes:
I installed Gallery 2, and after much frustration with the cart options it comes with, I discovered there is a Gallery 2/Zen Cart integration module, that allows Gallery 2 to interact with Zen Cart 1.2.7 (not the newest version).
Finally, I signed up to another 2CheckOut account so I could charge using credit cards without a merchant account and this is the result:

As stated, it is a work in progress, so comments are welcome. Also, do not try to place an order unless you actually want the picture, since the site is live
Thanks in advance for all your comments,
