Downloadable Products/Batch Image Upload, etc.

I have a long time client that went and purchased an existing website that had the ordering system created using ColdFusion.  Of course, the client has thrown a few things at me (wish they would check with me before purchasing something). And I am so not a ColdFusion developer.

Background on the site.  It is a photography site. A client is given a login ID that is unique to their gallery of images and once logged in they can view all the photos from their event (wedding, etc.) and purchase.  There are 3 different option groups.  The first one is the size (and downloadable product has been added there), then the finish but available for only 3 of the sizes, and finally a frame (which is only available on certain items).

1) He wants to offer downloadable images that are delivered after purchasing,

2) he wants to be able to do batch uploading of photographs

3) automatic watermarking (I've managed to tempoarily handle that using css and a .png)

4) batch ordering that can be compiled into an album

I have wondered about just separating out the downloadable option into a separate section, and maybe another one for give them all to me.

I do have an email into the original site developer about these options, if they are even a possibility, but thought I'd ask here.  And if I could locate components where in the heck do you add them?

As you can tell I'm a total newbie.

Thanks!
