I went to Ritz Camera and asked if I could get digital output from 35mm film. "Sure," they said, "There's a $4.00 fee for processing the film, and then $15 for a high-res photo CD."
$19. That doesn't sound very good. Plus, I don't want a CD-ROM. I just want to download the image files.
Online I found that Clark Color Labs, who I used a lot in the early 90s, will develop your film, send you a set of prints, and put your photos online for $4.28. That's more like it, but still—I don't want the prints. Snapfish will do the same thing as Clark, but for $4.98 a roll.
Why can't I pass on the prints? Oh, well. At $4.28 a roll, I can afford to take a lot of pictures.
[EDIT: It looks like Shutterfly will do it for $4.00 a roll, although only low-res images are available unless you order a CD.]
The digital preview images are not quite as large as I'd like, but nevertheless suitable for my purposes. Here are a couple samples:
