Blogger changes

i'm no expert in code, but recently Blogger changed the code when you post a photo. It's something I tried to scan on the internet, and found very little info. Maybe it doesn't affect anything, but in the end, it may affect some of you out there.

It looks like this. Why the heck did they decide to add this line of code in the last one week?

Basically, it was fine without it, and now it's in there... it does cause a problem with us for sure.
