If you use Windows and have the need to screenshot just the Runescape game frame:
Cropper 1.8 (246 Kb) [Installer]
How to use Cropper 1.8 to take a screen capture of just the Runescape frame and automatically save it as a file on your computer for later use:
(Quick Note: You will only need to perform all these steps once. This will set-up a way for you to quickly and easily take and save screenshots at the press of a button.)
  1. Download the Cropper 1.8 program.
  2. Install the program
  3. Run the program (It is most likely in Start > All Programs > Fusion8Design > Cropper)
  4. Right-click on the Cropper icon in the Notification Area (opposite side of the taskbar from your Start menu)
  5. Click Hide, then repeat previous step, Click Output > PNG, then repeat previous step, Click Options
  6. In the Output tab, set your Output Location and, optionally, the Output Templates (which determine how the file name will appear)
  7. In the Capturing tab, make sure "Use Cropper to save Print Screen images." is checked
  8. You don't need to do anything in the Appearance tab since we have Hidden the program, so, go ahead and click the OK button
  9. While playing Runescape (the game is active and your mouse is overtop of it), simply press ctrl+alt+PrtSc to automatically save a capture of just the Runescape game as a PNG
  10. You will only need to make sure the program is running and perform Step 9 from now on
  11. Optional: I like to make sure Cropper is running every time I turn on my computer by placing a shortcut to the program in my Start > All Programs > Startup folder.
(Special Note: If you're too lazy to dig around for where you're saving those screenshots, just Right-click on the Cropper icon in the Notification Area (opposite side of the taskbar from your Start menu) and click Browse.)
