Image Overlay Utility

A small, easy to use Windows program for displaying transparent, click-through images anywhere on screen!

Virtual tracing paper

Originally created for this purpose, Image Overlay Utility is great for displaying an image over any type of graphics software which lacks layers. The Click-Thru mode makes it easy to trace the image onto the canvas by making it to transparent to all mouse events.

Visual reference

Image Overlay Utilty can also be used to keep an image on-screen as a visual aid or reference. This can be useful for CAD and other artistic or technical purposes.


While not its original intent, Image Overlay Utility can also be used to display static logos/watermarks during live demos or presentations.

Easy positioning

The image overlay can be moved easily by clicking and dragging, and resized intuitively with resize handles.
