Platform: Windows 8 compatible, Windows Vista 64-bit, Windows 7, Windows 7 64-bit, Windows Vista, Windows XP, Windows Phone 7
Easily capture screenshots at intervals from every 10 seconds to few hours.
As with other more basic tools, Multiscreenshot enables you to capture the full screen, or a selected area. Images can be saved as JPG's or BMP's.
Selecting areas isnt the easiest thing to do but if you need a tool to take full-screen grabs over a selected period of time, it does what it says on the tin.
