There are cameras that do not support Mass Storage. Notably the Canon cameras for instance (PowerShot, Digital IXUS, et.al.) and others.

Second, Windows has several methods to interface with digital cameras. One of the is direct filesystem access (works just fine). The second is TWAIN. Originally just for scanners it is also used for digital cameras. On third, WIA (Windows Imaging Architecture).

WINE already had a TWAIN implementation (written by Corel during WordPerfect 2000 times) but it was only able to use SANE, and not really able to use libgphoto2 in a good way.

So what I did was to just add the lowlevel libgphoto TWAIN driver to WINE, and CodeWeavers provided a gphoto Import GUI for it. My part of work was small compared to the stuff the CodeWeavers people did.

Voila - importing from any kind of cameras into Picasa.

Btw, I think all of this is in regular WINE 0.9.14.
