Have you been noticing all your Flickr friends showing off their rubiks cube photos? I have. So I decided to figure out how they were doing it and I was quickly lead to Dumpr. Yes, that is its real name. Dumpr.net offers a tool set for turning your exisiting photos into works of art. Dumpr offers some unique online photo manipulations options for your photo uploads, links to photos and photos directly from your Flickr account. It enabled me to create my own rubiks cube photo just like my friends - don't worry I did not actually get trapped inside the cube to take the photo (below).
Dumpr is fairly easy to use and offers a number of its manipulation options for free. It also provides a pro offering which is priced at $3.99 a month. Once you create a new image you can share it to a number of social sites in addition to uploading it back to Flickr (which accounts for all the Flickr photos I recently noticed). Additionally, new photos are put into your own personal gallery.
If you can work with Dumpr's slew of text link ads you might want to give it a try. I don't fault them for putting up link ad units when they give away so much for free.
Enjoy!
