I must say that the mash-up tools are quite fun and can see why people spend loads of time playing with these tools without realizing it. I used Spell with Flickr to spell "I Love My Library" and was actually able to upload the picture using the URL. I had tried using the URL to upload other photos from Flickr yesterday and failed. I must be doing something right finally!
I also downloaded a photo I had taken on a trip from Picasso and used the Flickr Caption tools to create some fun lines.
I normally only share my personal photos with family and friends on Picasso as I'm a little wary of having them open to the whole world to view.
