Is there a way to do it ? I can't see the option in this forum either.

There is no need to enable it. It should just work. 

Testing …

 

I dont think so

but it works with the tags ... added.

so, how can I enable the tab for for those members in my forum that dont know how to do it ?

Do what?

that tab - Insert other media (which half of the times I try to post blocks me from posting) - is the problem.

you see,  it is not intuitive

in most forums - there is an image tab

media - usually is reserved for movies

Insert other media does not inform that it includes images

if one clicks the insert other media, a Insert image from url tab pops up.

if you don't , you don't post an image.

If you don't speak English - it can be quite confusing.

 

 

I edited it - in the English Language option as :  Insert a photo or an image
