I have an office open that has a couple texture organizers with a bit over 4,500 free textures in them. There are Christmas/Holiday textures in there but if you're looking for just the holiday textures without having to search then there's a box that contains them sitting on a bench.
There are also two photo studios in there that I've got set up for anyone to use. I don't have instruction cards for them yet but one is pretty simple, you just click on the backdrops to change it.
Last but not least I've placed Luneko's New SL Resident Resource Kit in there for anyone to take as well. It's a very good compilation of information that I wish I had when I first started out.
The only thing that isn't free are the photos I have hanging on the walls. Those are photos that I have personally taken with the exception of two that were taken by a friend. They're moderately priced at $100L each.
This office will always be open and free to the public as long as I have an account with SL. I've pasted the SLURL below. If that doesn't work you can always look at my profile and I have a landmark in my Picks.

Have a happy holiday season all.
