Sounds like you have a file conversion problem that would need to be handled at your end using appropriate software. Photoshop (which I use) can read and write several picture formats such as .gif, .jpg and .pdf. Word (the old version that I'm familiar with) can incorporate pictures (.jpg at least) into a .doc file but I don't think it can spit them out again later as separate .jpg's.

One rather crude solution is to display an image with whatever software is able to open it, get a "screen shot" of it with Alt-Print Screen, open the screen shot in Photoshop, crop it down to just the picture, and save the picture as a .jpg. The resolution you get will be no better than the screen shot that you started with, but still better than nothing.
