DEVONtechnologies has updated PhotoStickies, its Web cam and image viewer, and ThumbsUp, its thumbnail image generator. PhotoStickies 5.1 now displays images with full opacity when the user moves the mouse pointer over it, features “Copy/Paste Filters” commands and adds shortcuts to switch between the four areas of the Inspector panel. ThumbsUp 4.0 now also generates thumbnails of QuickTime movies. PhotoStickies (US$12) and ThumbsUp (free) require Mac OS X 10.2 or later.
