DropImage v1.0
Painfully basic drag-and-drop file resizing/converting utility.
Supports any image type supported by Image Magick (100+ formats) for which it is a front-end. Supports multiple file and folder drag-and-drop for batch processing. Resizes images to fit within an NxN square without distoring aspect ratio (default N=800 pixels) and converts to jpg. Fantastically ugly, but perfectly functional.
