You still can, it's just a little tricky.
(1) Click on photo in photostream to get it on the page
(2) Click on "Share"
(3) Click on "Grab the HTML/BBCode" if needed (I think this is sticky from whatever you last did)
(4) Click radio button for HTML if needed, and select size
(5) Snip out just the actual photo URL
Step 5 is probably the hardest, it's easiest to cut and paste the whole thing (with the angle bracket a href=...) and then remove the unwanted parts. This should leave you with just "http://farm<n>.staticflickr.com/..." URL.
For example, here's my new garage as of one week ago (it looks about the same today except there are more dangling wires :-) ):
(House still won't be ready by the middle of August, when I should get my Laguna Karma... sigh)
