I noticed lately that many highres and absurdres pics aren't properly tagged as such.
Since those kind of tags depend only on image dimensions, opening tabs and looking at every single pic isn't necessary, so I thought I'd fix this myself using tag scripts and search queries like height:>=1200 -highres or height:>=2400 -absurdres etch, but the amount of posts I got as a result was much larger than I expected.
I don't know what kind of tools mods and admins have at their disposal, but I thought I'd let you know in case it's easy to do and you feel like doing it.
