I've been using WordPress for nearly a year and never had this problem, but today I wrote a new post and tried to add some pictures and they won't show up. If I attempt to insert a picture to the post, it'll appear in visual edit mode, but not in HTML edit mode or preview. I tried several different pictures to make sure it wasn't a problem with the image file itself, and I even copied and pasted the entire post into a different draft to see if that would help. No luck. Also, I managed to add a gif with no problems, and I haven't changed the template or anything.
Any help would be greatly appreciated.
The blog I need help with is impendingdawn.wordpress.com.
