ImageMARK is a tool for annotating pictures and basic vector drawing. Your annotation is kept in a separate layer and can be saved separately for further editing.
Also, the annotation can be exported in PNG or JPEG formats jointly with the background picture or without it.
To access properties of annotation elements right-click or double-click them.
In addition to the cliparts on the left panel of the tool you can drag & drop small images from your computer.
Before using your background image you can downscale, crop, or rotate it using Imaging.
