It's visible on mine after allowing a bunch of scripts but I'm missing random images in general (I don't know why, also missing the summoner images in steem monsters so who knows).
Good website shouldn't require manual anyway. I'm sure you'll find your way around XD
Oh maybe going to check that also you don't have a hover to see info about the button like tag or a link in bottom. Well what I also see is in posts of others is links to images while on busy you see the image itself....
Exactly it's all about usability and logic :)
