I spent a great deal of time trying to pick good examples of Flickr mashups and tools for the project blog. Some of the ones I tried I could not get to work correctly. I liked the "Spell with Flickr" thing, so I used it, but it took me a long time to figure out how to actually save the image of the words spelled out with images. (I ended up doing a screen print, (Ctl-Print Screen) and then had to paste it someplace, so I opened up PowerPoint and pasted it into an empty slide, and then saved the image. Then I had to use a photo editor to crop it and resize it. So it wasn't simple.
I find most of the Flickr things to be kind of dumb, and they don't appeal to me. But then I'm not really that big on pictures anyway. I do realize that some people are more "visual" than others and that images can be a very strong way to communicate.
I tried an application called fotocrib and used it to alter my picture on my profile.
