Missing Labels for Screenshot/Media (and too small!)

Adding screenshots now - there is some potential customization via the gear icon and dropdown menu. However the labels are missing. The middle option brings a dropdown box with three options. The top is default tiny size, the middle allows the user to set the width in pixels of their screenshot, and the bottom I think is max size. However it adds a bunch of compression or something. For instance my native screenshot is 2556px but when I set it to that size it blurred it heavily... icky.

But in the end when I posted, this forum shrunk them back down to tiny anyway. Is there a way to get back to the hi resolution screenshots? I'm only on a 1440p monitor but the final shots are basically less than half the width of the forum! It's like looking at thumbnails - one can hardly see any detail in the pictures.

(here's the pic but it's tiny - may be hard to see what I'm talking about lol)
