Having a problem....

My picture's are suddenly nasty little red "X"'s...wonder why they wont load?? Have I got to many?? (Say it aint so! I love my pictures!)
I had to do away with my videos as I couldnt load my blog at all. The problem turned out to be Dial Up. I am now using peoplepc as a server (until things are in order and I can get back on Comcast) and for the time being it is much better than netzero ever thought about being and less expensive too!!
Back to why have my pictures become nasty little red "X"'s? And I just discovered I cant upload any either!!
Have the settings somehow changed? And if so, how did they change by themselves? And where are they? It's like the Blog Monster has taken my blog away from me!!
