I've sometimes had problems with the upload, too (it might 
have to do with the connection) - I would include an 
active in-line link with the message, but I hope people 
realize that using an active link also means people are 
pulling the image bandwidth directly off the server your 
site is on. This may not be a problem with the free servers 
like Geocities and Xoom, but with enough traffic (I doubt 
it), it can get your account cancelled. And, for people 
who PAY for their web hosting like me, out-linking bandwidth 
is always a bad idea (even though my traffic allowance is 
400MB/day).
