Gallery single thumbnail

Hello and thank your for reading.

The problem I’m facing is i need a single thumbnail gallery That works both website side but also renders correctly for Facebook Instant Articles.

Now i have hunted for the last few days and came up with nothing that works so if anyone could point me in the right direction.

Template were currently using is ENFOLD but the creator of that for some reasons hasn’t made it so it can render correctly for Facebook Instant Articles.

The single thumbnail stuff i can get working website side not a problem using css but when rendered for Facebook Instant Articles i just see the short code.

Now i have tried WP gallery but they look horrible website side but amazing FBIA side i just cant win!
