NEXT_GEN Gallery, tag an image

Hi there,

My client wants to have an easy life uploading his images. He wishes to have his images appear in both pages and posts but only uploadning them one place.

My suggestion is to create a gallery where I tag the gallery to a page. Thereafter go to post and insert the ID for the gallery. In this way he only has to upload the images to the gallery, add the information here and then insert the link in the post.

Is this the way to do it, and if so, how do I create tag the gallery so it’s shown on a page?

Does he really need to go in and insert the galleri ID for both the post and the page?

If no, what is the alternative

I hope it makes sense

Thank you
