My cow ran off with my flag
Don't you hate when that happens? That means that the server I've placed my images on has failed, no doubt due to the staggering weight of page views that my readers (both of them) have given me.

If that were all I needed it for, I'd just go imageless -- but it also means that my other, non-blog pages are also inaccessible. Think of it as an early warning system. Some people have a canary in a coal mine: I have a cow in my sidebar.

Someday I'll upgrade to a real server, instead of Mattel...
