Many Yahoo photos users will soon be making the exodus to Flickr, so we thought we'd give everyone the heads up on a fairly cool "event" going on tomorrow. It's called 24 Hours of Flickr, and it's challenging people to go take pictures all day Saturday and then upload their favorite shots to a Flickr group specifically created for the day.Flickr editors will go through the photos, pick some of the best, and add them to a coffee-table book (designed using Blurb) that will be made available for purchase this summer.
Anyone who gets a photo in the book gets a free copy. For everyone else, the book will be made available for the cost of publishing, with $1 of every purchase going to humanitarian group Medecins Sans Frontieres.
If you're unsure what Flickr is, or how to use it, check out our Newbie's Guide. Users will have until May 21st to upload their photos to the group. More information and updates can be found on the 24 Hours of Flickr group.
Both Cinco De Mayo and the Kentucky Derby are happening on the same day (and that's just counting North America), so pictures will likely be very interesting. Flickr groups for both events can be found here and here.
