(1) Flickr is owned by Yahoo, so setting up an account there required zero effort. On previous days, I had learned that my two most reliable friends for tech suggestions both use Flickr, and neither one has any affection for Picasa.
(2) I learned that .sfw was a proprietary bitmap format for Seattle FilmWorks.
(3) That is what my photos are stored in on the 4 CDs I have. 4 CDs is a whole lot less than the total number of rolls I have in the box. While the SFW CDs have executables on them, they are all designed (this is a duh thing, if you think about it) for the Classic environment, no longer supported on the MacBook I currently use.
(4) But which _is_ supported by the iMac upstairs. However, I don't think it's worth the trouble. I think I'm going to take all my old rolls of developed film (ahem, I'm not mentioning APS because everyone hated it, even tho it was very kind to me) and have them digitized in something that isn't proprietary and isn't already out of date.
(5) Probably using Costco 1 hour. That's what R. suggests. Learning about that is the next step.
ETA: (6) Definitely not using Costco 1 hour. Probably not using Costco. They say they fit scanning jobs in between other jobs and it is time consuming. They predict 2-3 weeks to get through the 60 rolls I have and won't commit to getting even a couple done in less than a day. Thus,
(7) I have a request out to the (closed on Sunday) local shop. Their pricing will probably frighten me -- but they're local, and that counts for a lot.
I'm not prepared to say this is fun, however, it is learning.
