Using ThumbsUp you can easily drag-and-drop batches of images to create thumbnails. It supports any and all image formats supported by Mac OS X and QuickTime (including PDF documents).
- First things first, download and install the small (and free) ThumbsUp application from Devon-Technologies. Just open the zip, then the .dmg, then drag ThumbsUp to your Applications folder. Launch it from there.
- The Preferences window will appear. From here you can define how you want your images to be created – everything from size, quality, file type to name.
- After you’ve set the preferences to your liking, close the window. Drag one or more images – or folders of images – onto the ThumbsUp icon in your OS X dock.
- And thumbnails will be created for each and every one of the images. The output format, name etc will all depend on how you opted to set up ThumbsUp.
