I'm talking about photos of any ants, not necessarily your own. I don't think it would be appropriate to post photos of wild ants in the journals section. I also think it would be a good place to put nice photos of your own ants, that aren't really for illustrating the progress of your colony, but are aesthetically pleasing. Furthermore, not everyone who takes photos of their ants wants to keep a journal of them.
Now that you mention it, I do have some pictures I took of some ants in my backyard that aren't good enough to use for identification purposes, but feel good enough for sharing. I'd post in a thread or subforum though.
Besides, General just seems so lonely when I'm navigating the forums on my phone.
