pmView is not a painting program, but has got more functionality than a simple image viewer. It's very stable, fast and multi-threaded.
The address of pmView is http://www.pmview.com
It's the most useful program for the default graphics file association and a substitute for the ugly OS/2 multimedia viewer. If you save a graphics file, you'll get an icon of your graphic.
"Only" the following graphics formats are supported:
*.BMP *.CUR *.DCX *.FIT *.GIF *.ICO *.IFF *.IMG *.JPG *.LGO *.MAC *.MSP *.PCD *.PCX
*.PIC *.PBM *.PGM *.PPM *.PNM *.PNG *.PTR *.RAS *.RLE *.SGI *.SHW *.TIF *.TGA
*.WPG *.XBM *.XPM *.XWD
There are BMP- and ICO-formats both for Windows and OS/2.
You can convert between these formats, then there's a slideshow mode. When saving in GIF file format, you can optionally set "interlaced" and choose a transparent color. (Color index 0 is the color placed at the beginning of the color palette.) You can rotate the image or change the size. Most of these functions have got a dialog window with special settings. There are a lot of filters.
