Web 2.0: Online Image Editing
Many simple adjustments to images can now be made with free Web-based tools. There are also some new tools out there that create and manipulate image that you can use for classroom activities.
Wordle

Text analysis software usually presents word frequency. Some of the visualization and text analysis tools out there produce complicated results using concordance and word counts, but there is one simple one:
Wordle is a Web-based tool that creates “beautiful Word Clouds” from your words and phrases. It creates visual representations of word frequency. Sometimes called “tag clouds,” or “weighted lists,”
word clouds create visual representations of concepts and words. This can help students think of words and concepts in a different way. Wordle looks for commonly occurring words,
which is why it is such a great tool for analyzing narratives such as literature or speeches. Wordle frequency enables students to interpret, qualify and visualize text in new ways.
