The Windows XP versions are capable of saving in jpeg format.
Old test results
The test results you have selected are very old and may not represent the current state of Wine.
Selected Test Results (selected in 'Test Results' table below)
Basically everything I've used (I've used only really basic functions) except whats written bellow.
What does not
From what I've used I can only tell that after you use the secondary color of the pencil tool it keeps using it and "overwriting" pixels on mouse over, this really makes it hard to drawas you need to fix your drawing if it happens.
Another very important thing:
When you click on Print Preview under the File menu, the program crashes immediately. So watch out not to click on it as any unsaved work will be lost.
Other problems but minor ones:
when you move your mouse with a tool as the pencil or the eraser, it messes up the pixels of your drawing (but you can only see that when you zoom in), it doesn't affect your work, but it can get annoying.
When you zoom in, you can't see the horizontal scrolling bar until you click on where it should be.
What was not tested
I didn't test the airbrush, brush, text, and shapes tools, the printing or flipping/rotating.
I've tried to use MS Paint for pixel art, so I've only used the tools I really needed.
Take the file mspaint.exe from your Windows XP/NT/2000 system folder, as well as the file MFC42U.DLL. Put these both in the same folder somewhere with wine.

One work around is that once you are done doing whatever with the secondary color, left click and then press control z (to get rid of the one spot of primary color. It's a somewhat annoying, but overall very quick, work around.
Additional file formats

I have found that with just mspaint.exe and mf42u.dll, paint can only read the bmp file format. If you put GDIPLUS.DLL (I got mine from an office install, thanks wasabi) in the same folder as the aforementioned files, then paint can open and save to gif, jpg, and png. I have only tested saving and opening PNG, but it works fine.
