This is a very strange problem. I've been using ME without issues for some time. This morning, I went to write a post as I normally do. I uploaded an image to my server, and then I added the code for that image to the post. A blue question mark shows up in the preview area. I copied & pasted the URL into a browser, and the image appears there just fine. I then tried using a URL for a previous image I had uploaded to my server for another post. It displays in the preview window in ME without a problem. I tried several other images already on the server, also no problem. So then I uploaded another version of the image that won't preview. And it still doesn't preview. It seems that the preview won't work with any image that I have uploaded to my server today. Any ideas?
