I use postimages.org . No need to register there, no nasty/timed redirects.
Click their "Choose Image" button. Uploads are fast ~3minutes for a 1920x1080 screenshot; though I try to 'crop' images to a useful size to cut down on upload time.
Use the "Thumbnail for forums:" is best IMO and it is already formatted for the forum; just right click the text line, copy and then paste into the HGpost.
If it is a large image, shrunken too much as a thumbnail, I include "click thumbnail for larger image", under the thumbnail.
Have not had any complaints from Staff, yet.
happy gaming

PS: I have seen large images filling the post width so that is probably OK.
