Links to pictures

I've noticed just now, not sure how long it's been this way, that when I link a picture in a post(rather than uploading it) it's different than it use to be. With links pictures it use to be that there would be no bar on top of the picture saying "Undefined", when you would click on the picture it would just make it larger, now I have to click the 'undefined' bar but it brings me to the webpage.

I use Dropbox when I post pictures to make it more simple for me.

Is this the normal now?

Here is an example of the bar that appears on larger pictures.


Here is a larger picture to show the bar again.

Yes it the way it is now, he's been working on some things for a while to make images load easier.

Oh I see why now. Thanks for clearing that for me. People with less bandwidth won't have to download the whole 1.5MB picture now, just a smaller preview.
