Bulk Image Resizing Thing 1.2.1

BIRT, the Batch Image Resizing Thing, is a simple application that allows a large number of images to be resized in one go. Obviously this is possible by scripting ImageMagick but its usually somewhat easier with a GUI.
Bulk Image Resizing Thing was created in order to learn how to develop using the Qt library, and to facilitaty the maintenance of an online photo album where each hi-res photo needs a low-res copy and a thumbnail.
Usage
BIRT has a hypertext based online help system (visible in some of the screenshots below), to access this simply start the application and click on the Help button at the bottom of the BIRT window.
If you cant wait to read the help then here is a basic guide to using BIRT: simply select the image files to be resized, enter the new size, select the output directory and press Go. A more detailed instruction set, include explanations of the ratio options and output suffix/prefix fields can be found in the How To Use BIRT section of the help.
Enhancements:
- A problem with the Help dialog that would prevent it being re-opened if it was closed using the systems close window widget rather than the "Quit" button was fixed.
