WetGeek I'm just a little curious (and envious) about how you can post full-frame images to the forum.
I get the screenshot ("png"), reduce to 50% (that is, 1920x1080 > 960x540), then save as "jpg" to cut file size (png is wasteful, jpg more efficient). The end result is a file about 10-15% of the original size (that is, 150-175kb rather than 1.2mb). At that point, I copy it in. I resize, as noted, but simple conversion from png to jpg without resizing drops file size to about 30% of the original png screenshot, and allows it to load.
