For Photoshop 7.0
Once you
created a graphic, texture, or whatever, that you want to use as a brush,
you have to get the brush into your brush-list, so when you press on the
Brush or the Eraser Tool in your Tool bar, the new brush is at your disposal.
To achive this click (Edit>Define Brush).
When the name dialog box appears, give your brush any name you want.
The name you gave the brush is of no consequence
The Brush is now an icon in your brush menu. You can use it right away
and do not need to restart Photoshop or anything. It doesn't disappear
if you close the programm, only if a system failure shuts it down or the
programm doesn't respond for other reasons.
Now all you have to do is select the brush tool (see right) and then select
your brush from the Brush
menu,so you can use it for your graphics.
ATTENTION!
Be careful not to RESET
BRUSHES in the brush menu palette. Once you do that and have not saved
the Brush(es) you created as .abr file, the brush(es) will be gone.
The same will happen if you choose one of the Brush sets in the same list.

next tutorial.
