You will need the following programs:
Dropbox (I have lots of invites for it, so you can pm me if you want. Include your email or I'll ignore it)
Download and install both programs (and register for dropbox and whatnot)
Your Gadwin Printscreen preferences should look like this:
As you can see you need to have it save the screen shots in your dropbox public folder. Dropbox then automatically uploads it.
Now to take a screen shot.
Hit printscreen, then select the area you want to take a picture of, and right click.
Then right click the drop box icon
in the bottom right of your monitor.
Click on Web Interface
This will open a new tab in your browser.
From there click on Recent Events, then you can get a direct link to your image.
I know I didn't explain this in minute detail like other guides do, but anybody with half a brain can figure this out from the basic description I gave.
