Screen capture on Mac OS is a fantastic way to take information around with you on a mobile phone. Of course, if capturing many different items, you need to label them. This hint shows how to use Automator and AppleScript to make this a one click process.
First, build an Automator workflow (choose Application from the template chooser) as follows:
on run
(*
Replace Text In Item Names
This script is designed to replace text in the names of specific files and/or folders in the front window of the desktop.
If no folder windows are open, the script will affect files and/or folders on the desktop.

You will note that the process is a bit cumbersome -- Automator first renames files to Picture..., then the script asks you for what you want to replace Picture... with. This is just customized from Apple's own Finder script. The latter used to work fine on its own pre-Leopard, when files were prefixed just with Picture....
The cleverest part of getting this to work is not mine. I had to edit the script because, in Automator, the number of items in command kept giving an error (No result was returned from some part of this expression). I needed to replace this with count as I read in this forum post.
OK that's all to read. Hope it saves somebody lots of paper like it did me!
[robg adds: I tested this, and it worked, but only if I set the search scope in the first command to Desktop. When set to Computer, it didn't seem to work. Also, if Automator would simply let you place a variable into the "New Name" field in the "Make Sequential" step, the entire AppleScript could be avoided. Alas, I couldn't find any way to do that.]
