I created a folder of buttons for my school to use in their courses. I can't seem to share the folder to commons. I can share a single image, but not the whole folder.
Looking at the options of what you can upload to the Commons, I would suggest creating a module with all your images. Then share that module to Commons. Users can then import the module as a way to get the files into their course. They can easily preview the images by navigating through the module. They can choose to delete the module, and the files will remain. They can then add these images to pages, quizzes, discussions, etc.
TIP: If you are sharing it with the public on the Commons be sure none of your images are copyrighted. If they are licensed Creative Commons be sure to credit your sources.
Hope this helps!
