I've looked around and I'm surprised nobody seems to have noticed. About a week ago, it started. I think it started around the same time that new notification was sent out telling u "New! Add multiple photos, message friends of friends and more." at the top of your inbox/full conversation mode. Usually the "Press to Enter" box is always checkmarked because that is the setting I always used. But I noticed that when I use full conversation mode (messages inbox, not that little chat window pop up thing), I send a photo and it used fill out the entire message area. Now I had to recheck the "Press Enter to send" box as if it got reset automatically, and the picture now appears very small, only fills about half the space of the message area. I've checked on multiple accounts I have an it has affected nearly all of them now. I still have a couple accounts that the pictures show up fine but I'm not sure Facebook is in the process of switching everyone's account over to this new format or if it's just a glitch in their programming due to this new update I mentioned above. It's really annoying because now the pictures appear so small I can barely make out details and it hurts my eyes (like I need to get glasses if I keep staring at small images). Of course, if you click the photo, it still opens up in a new window full size, that's not the problem. The problem is I'm used to conversing with friends inbox full conversation mode (not chat box mode) and sending photos back and forth but now they are tiny. Here is an example screenshot I took side by side of one account which is doing the small photos now (left) and the other account that is working how it always did, larger pictures (right side). Anybody have any clue as to what is going on? I reported it to facebook twice asking about it and nobody has responded. Why would they squeeze and make pictures so small? It was perfect the way it was before. and this is the new notification everyone got at one point inbox at the top...and I think you had to re-click the "press enter to send" box again. Did yours get cleared, too? You might have tried to send a message and kept pressing enter wondering why the heck it wasn't sending, then realized the box was unchecked oddly, but probably didn't think anything of it and just continued on.
