Good overview of the community standards for using images, that should not only apply for Steemstem.
I just wonder, why you didn't use tags like #creative-commons #public-domain #howto or #guideline instead of #science #technology #engineering and #mathematics ?
Because I'm ignorant... I write and work for SteemSTEM, i habitually limit myself to a few of the same tags lol. No idea you existed until now!
