ImageGlue is small program to crop and glue several images together.
You can either drag and drop image files to main window or click "Add" button to open them one by one. Select a file and click "Remove" to unload images. Each image can be cropped and moved relative to glued image's top-left corner. Blank areas not covered by images will be filled with white. Negative cropping will fill areas outside the original image with black. Clicking "Preview" will create, or update, preview and allow you to click "Save" to save the glued image.
