For those interested, the athenaeum.org is an online art image library that regularly (irregularly) updates their archive. They may go nine months without an update and then, usually in the fall, they'll upload hundreds of new images in a matter of days.
If you click the link above, you'll see every picture they've uploaded in the last 7 days. This changes every day as time passes, so if you're like me, and you want to save them to your computer, you have to act fast.
Last night, they uploaded about 100 William Merritt Chase portraits, and some Sorollas -they've been adding to these two artists for about a month now.
I'll post updates anytime they put out a good update. I used to do this on Facebook, but none of the people I know really seemed to care.
Oh, one note. Every once in awhile, you'll come across an image that they fear is under copyright. So they only allow you to see the thumbnail. This may be some technical error on their part, because the art is almost always at least a century old (at any rate it always seems random). If you just change the word from 'detail' to 'full' in the address bar, you can see the large version.
