TCel empowers front-end web developers to get their webpages pixel perfect. While laying out a webpage, overlay an image on top of Safari or other web browsers and truly match what your graphic designers intended. See TCel in action: .

- Supports many image formats like PNG, PSD, AI, and JPEG
- Control the opacity of the image overlay
- Use keyboard arrow keys to exactly position the image overlay
- "Ignore Mouse" to click through an image and interact with applications underneath
- Invert an image where color differences are hard to make out with the naked eye

What's New in Version 1.5.1

- Fixed bug where TCel crashes for OS X v10.7.5 Lion users; thank you, Yoram, for the crash report.
