I completed teaching a course in graphics recently. I got really excited about the multitude of graphic online Web 2.0 Tools available. One can take photos, upload them, manipulate, and share them. Here is an example of an architectural photo I took in the Czech Republic, altered in Lunapic. This is really fun experimenting with effects or filters that mimic results in high end graphics software. Is this an option to jazz up your sites? You might want to try it! Do you have other tools you could share with us?
