I just tried to include a image in a answer and the system didn't let me. I used the same procedure I always do, which is to type ctrl-G, then enter the name of the image file on my disk. When I hit ADD PICTURE, it popped up a window saying "Are you sure you want to navigate away from this page? You have started writing or editing a post. ...". If I try to upload again after that it pops up a different window that says "For security reasons, framing is not allowed ...". I would upload screen shots if I could, but I get the same problem trying to upload images here in meta.
Please fix this.
While you're at it, it would be nice to fix the long-standing bugs in the Add Image dialog. When I type ctrl-G, the Add Image dialog pops up. There is a place to enter the image file name with a BROWSE button immediately to the right of that. The stupid thing though is that you can't type in the file name line. You have to click on BROWSE with the mouse, which then pops up another window the finally does let you type a file name. I really dislike being forced to use the mouse. It slows down the flow and requires concious mental intervention as apposed to typing. This has been broken since the last change to this diaglog maybe a year ago.
At least some others are not running into this problem, so I'll try to provide some screen shots. Since I can't upload them I'll put them on a server and provide the link here.
Here is the result of trying to add a image into this post:
