When I saw this image, at first I found it was blurred and somewhat pixelated…
But when one click on it, the new window opens it at the original scale it was posted, and the picture is more than fine…
Because the forum software by default enlarge the picture to the full width of the window.
This should not be a behavior by default. This might be the result of the developper thinking that only smartphones do visit fora… Not my case!
If this cannot be resolved in the admin console, note that if when once an image is post, one reduces manually its size (by dragging one corner) the image won't appear full width…
@Asher Kelman, imho "GHO" stands for "
Great Horned Owl"
@Don Ferguson Jr. great catch!
