Shows just fullsize Image with hotkeys & without pop-ups on many image-hosting sites
Open page https://github.com/Owyn/HandyImage/configuration to see config
404 Page not found
EDIT: the page seems to get messed up by Handy Image, but I can't see any settings. Is there a way to edit it back manually?
Handy Image doesn't run on the direct image url,
It still runs on pages it later counts as incorrect ones and stops there.
for example: http://imgbox.com http://radikal.ru http://imgfantasy.com http://bayimg.com
open one if these links and then go to GreaseMonkey dropdown menu and select "UserScript commands -> Handy Image configuration"
the page seems to get messed up by Handy Image
yup, because firefox users never get to see this page, it's a workaround for Chrome users...
I was able to reset the settings by uninstalling and reinstalling.
[Help] Changing direct image setting back to normal
Handy Image redirects the image page to the direct image url. However, Handy Image doesn't run on the direct image url, so the settings page can't be accessed.
