This example shows how you can create a simple Flickr image search with YUI3, but I have extended it to include the ability to save the files to folders when you drag and drop them on the folder of your choice. I will look at adding the ability to add and modify folder names at some point in the future.
Click and drag a photo to an album above. You can also Shift + Click to select and drag multiple photos.
Click on an album to view the photos that you added.
You can also use the slider at the bottom to adjust the size of the image to help fit them on your screen.
