UPDATE: As luci pointed out in the comment below, Tiki's image syntax has an imalign attribute that accomplishes the same thing as this plugin, so that's definitely the easiest way to align an image and flow text past it. (I really need to keep up with changes in wiki syntax. ) The IMGSTYLED plugin does also have clear and a few other properties, though, and I noticed the imalign doesn't work if the desc (description) is also used, so in particular cases this plugin might be a better choice than the wiki img syntax alone.

{IMGSTYLED(margin=>2px, float=>right, clear=>none,border=>solid 8px grey, width=>160px, height=>120px, title=>kapaa_theme, alt=>kapaa_screenshot)}show_image.php?name=kapaa_160_120.jpg{IMGSTYLED}
