Hey respected mods I am new to sakugabooru and today I posted a really nice keyframe from Irregular at magic Highschool I added all the tags needed into it and followed the rules and it was posted but after some time it was deleted reason given was lq I can't understand what does it even mean please help I am confused

lq = low quality

only high quality scans and/or interesting production materials are archived here. Otherwise the site gets flooded with them, they're too easy for just anyone to grab off the internet and post

From what I can tell your upload was a gif? try making it an mp4 that's much more useful and will also retain the original frame rate, so it should pass that way
