I just tried for about 30 min to add an image the old way, by using the attachment button on the bottom of the thread. I took it down to 5" x 5" at 72 DPI and it still wouldn't take it. Way smaller that any image I had posted in the past. I think it was less than 1/2 a meg. I hope this is something that can get resolved, as this is a much easier way to post an image without going to my photo gallery and upload it there, then have to relink it to the post. I did do that for an image I just posted and determined 144 dpi at about 1400 x 1400 pixels worked well. My first image was 2800 x 2800 and was way too big for the screen when linked.
I hope we can get the easier way to post an image fixed, as I much prefer that method, as I think a lot of us feel likewise-
