If you take a snapshot for in-world use (that is, not a Save to Disk picture, but one that costs L$10 and goes into your Photo Album folder), a window opens showing the image with a text field to give it a description.
While a description is all well and good, what this window REALLY needs a place to enter a name. Right now, the only place to name it is in the inventory window, which may not even be open at the time. Almost all of my snapshots are called "Snapshot" unless I went through my inventory opening random images and naming them. (Even then, it still takes two windows to do that, one to show the image, then back to the Inventory to rename it.)
While we're at it, since the Snapshot format goes so far as to have a different icon from textures (though can be used as one) it would be nice if it retained the photographer's screen ratio and defaulted to that shape. (Instead of showing itself distorted and squished as it does now.) It would just be a single float.
