2 * technikum29.de | Unobstructive Copyright Information
3 *
4 * Since there are so many people copying pictures from the website without
5 * even knowing ot the copyright statements on the imprint, this jquery based
6 * script implements some rather "unobstructive" ways of informing them:
7 *
8 * - hovering a picture replaces it with the "hotlinking picture"
9 *   (see http://dev.technikum29.de/src/hotlinking), that is, an embedded
10 *   watermark / copyright tag
11 *
12 * - hovering some more time over the picture yields a small informative
13 *   box (containing the alt-label of the picture) that informs about the
14 *   copyright message
15 *
