Mark Hamstra at Modmore has this:
https://www.modmore.com/moregallery/
I think this part of the documentation should clarify if you can achieve what you want
https://docs.modmore.com/en/MoreGallery/v1.x/Snippets/mgGetImages.html
I think MS2Gallery is for the minishop extra. Wholeheartedly recommend moregallery as Andy suggested.
Take a look at the demo here:
https://demo.modmore.com/manager/?a=resource/update&id=3
You can see on this page you can setup a resource gallery but still have content fields, tvs and everything else.
When a resource is converted to be a Gallery it is still a resource, with the Content, TV's etc.
If you were working on a new site this would not be a problem.
If you are adding this to an existing site then yes, you would have to convert all existing resources to be Galleries.
It might be worth asking Mark at Modmore if there is a way of automating the conversion process with a plugin?
For example in the demo site if i want add gallery to about us page:
https://demo.modmore.com/manager/?a=resource/update&id=2
how can I do?
You don't have access in the demo but you would just go to the settings tab and change the resource type to gallery
