Many websites offer free Photoshop-brushes.
This site has collected a nice pile of them.

Some great brushes there - thanks. Looks like they are all from DeviantArt but that is such a pile and this site did a very good job selecting and categorizing that collection.

They just improved DA RSS feeds and I am pulling some top brushes on my site also - might be a good way to pull other related material for imageafter I guess -or you can create imageafter feeds. I'd love to add thumbnails of your popular items and send more people your way.

. You can see my 'top 40' here http://stormvisions.com/pages/freebies/deviantart/photoshop-brushes-da.php if you are curious.
