I made a new sig and uploaded it to http://www.fhost.org/, where I've had an avatar hosted already.
The pic went up no prob, so I added it to my sig here in my control panel.
But something funky must have happened, because I couldn't see it when I checked it out in the image folder at FHost... just the all too familiar little red X in the white box. I tried uploading it again.. same deal.. deleted it then tried again.. nope.
So I went hunting for another host. I tried ALL the URLs in [B][O][T]'s pinned list and not one would work for one reason or another.
While I was host searching, I'd forgotten to remove the FHost'ed pic from my sig, and for some screwy reason it made a username and password pop up window appear everytime folks here tried to view a board page with a post from me on it.
I found another host for my sig.. but I have no idea wtf is going on at FHost, as some other images I have there seem to work just fine.
Many and profuse apologies to all that were inconvenienced by the annoying pop up.
As Eric Idle said in Monty Python's The Meaning of Life after poisoning the dinner party with the salmon mousse:
Sorry folks :'(I'm most frightfully embarrassed.
