Gridley is a very small but powerful Windows application that generates one image from multiple images. It can save you a lot of time in a variety of situations such as:
Combining multiple screenshots;
Creating photo thumbnail sheets;
Merging design mockups;
Positioning prototype screens in a grid;
Scale one or multiple images up or down;
Generating photo collage desktop wallpaper.
Over the past few years I constantly found myself needing a way to quickly merge (or scale down) screenshots, mockups and waiting for monster programs like Photoshop to load or clicking dozens of times Windows Paint was really starting to bug me. I looked around for existing apps or websites that did something similar and while I did find a few that came close none of them did exactly what I needed so ... so as the cliche goes I decided to "scratch my own itch" and I just built something myself. I very well may be the only person who finds the application useful but I'm already using it daily and am loving it.
