Apologies for red X's......
Sorry about the missing images. A couple days ago my computer crashed, and I had to log back into my web space provider (Freeservers.com) with a new password. For some reason Freeservers is treating this as a new customer, which requires a special suffix on the address. This 'probation suffix' will go away after a few days, I think... In the meantime, it's not worth editing a whole lot of image tags, because I'd just have to edit them back to the original when the need for the suffix is gone.
UPDATE: Talked to Freeservers. Turns out the domain had expired but I didn't receive any notification. They will be putting it back on line in a day or two.
Saturday morning: Appears to be fixed. Relief!
