Xzewd snapshots: installing them

# Installing a snapshot for yourself

Here's a quick reference, for people who've read the discussion below already:

- Make a picture. Not too big; XBM or XPM format.
- Install it as `~/.snapshot`. Make sure it's world readable!

And now, here's the long version.

First off, create a snapshot using your favorite drawing program. Try bitmap(1) for monochrome, XBM-format pictures, and xpaint(1) (`add graphics` first) for color pictures. (If you use xpaint, you should save in XPM Format.) Snapshots should be pretty small, so that several can fit neatly in a person's snapshots window. Anything less than 50 by 50 is definitely fine, although sizes up to 80 by 80 are common. In general, though, the bigger a snapshot gets in one dimension, the smaller it should be in the other; a 100 by 100 snapshot is too big, but a 100 by 40 snapshot is sort of okay.

Now, you need to install it in your home directory with the name `.snapshot`, and you must make sure it is world-readable. If your home directory is already world readable, there's no problem; just `mv` the picture to `~/.snapshot`. If your home directory is not world-readable, but you have a world-readable `Public` directory, here's a simple three-step process to install your snapshot. If you haven't understood most of this paragraph, this is probably the situation you're in.

    	mv picture-file-name ~/Public/.snapshot
    	cd
    	ln -s Public/.snapshot .
