We're pushing pics.livejournal.com (scrapbook) through some new servers, so performance will be much better. What that means for us is more reliability, faster uploads, and less headache. The service has been mostly left on its own for a while (2 years? more?), so it is due for an upgrade.
Sorry we broke things intermittently this afternoon. Everything should be well now, but over the next day or two we might make some minor changes and will update status.
