Yeah, I am using usually 30 - 60 photos on my posts, if I ought to use original resolution it would be a disaster :D Not to mention watermarks :)
Regarding communities and where to post, it's actually amazing how many places there are to post. This (Hive) is not a huge space, but it still has many "corridors", if that makes sense. Yeah! Happy to be here and open mind is a good way to look at it. : )
Yep, I am still discovering too:)
See you around!
