Link back htm resources

Often i use to download htm documents for reading things offline. Some of these htm-documents lose the link to their items (pictures) in their resources folder. Why? some hints how to repair and link back resources ?

Another question:
i get this warning trying to delete older messages in my message box of my Macscripter profile:

In short: i’m unable to get/receive other messages. i tried to contact somebody admin for help, but nope. Some other admin likes to care about it?
