@finnian, This issue with the images is just ridiculous.
I've been using the code you got from @teamsteem, but as soon as I switch back to the Editor (I'm not a coder, so getting stuck in the matrix too long gets me anxious :-) ), then everything goes to pots.
Surely we can get someone to help? Can you recommend someone/ a channel, please?
Editors do not work well. Steemit does not support all the code the other editors support. You are better off making a working template in a separate fire, and then copy and paste it into your new posts like I do. Steemit doesn't even support centering an image with text wrapped around it let alone some of the more complicated code. :)
