frustrated!

I have just been writing a super long post and trying to insert pictures, but for some reason it won't let me add more than one picture.  Has that ever happened to any of you?  Do you have a solution?  I can try a different computer later tonight but I was hoping I could figure this out so that my computer here at work will let me blog!  It's super slow sometimes (like today) so blogging is a productive way to let the time pass, right? :)  Let me know if you have any suggestions!
