Photographer & developer Thomas Menath has whipped up AspectFrame, a Flash panel for Photoshop CS4, and he’d like to get help testing it. (The Flash UI can also run as a dialog inside Photoshop CS3.) According to Thomas,

This tool is just for drawing rectangular frames around images and optional adding additional space to get the standard ratios of 4:3 and 3:2 with an optional cutting line.

For more info & to download the panel and submit bugs/feedback, go to the product page.
