ThemeShooterX released by Leathl

ThemeShooter is a small application made to allow HBC theme creators to create screenshots of their themes to put on the HBC theme repository here. ThemeShooter is Windows only, however there is a cross-platform, Python based version called ThemeshooterTK and a native Mac OS X version called ThemeShooterX.

Changelog

Added theme previewing
Rejects incorrectly sized images
Bubble positioning is now random (don't blame me if they overlap :P)
