Not sure how familiar everyone is with Flickr, so here's a quick tutorial on how to print your favorites from home. If you see a photo you like, you will find a menu of options directly above it. Click on ALL SIZES.

This will show you the photo in various sizes. You want the original size, which is the largest.

Once you have that version open, click on DOWNLOAD THE ORIGINAL SIZE. You can then save it to your computer and print it.
