Document how to group photoswipe images into a gallery in views using photoswipe-gallery wrapper class

Thanks for raising this. It's not a bug, but there's missing information in the README.md that needs to be added to show images from a Drupal view in a Photoswipe Gallery.

If not adding a photoswipe-gallery wrapper class in the view around, the photoswipe images won't be shown as gallery, but as single pictures. That's expected, but we should document how to group them into a gallery by adding the required photoswipe-gallery class.

@thomas.frobieter could you elaborate on that in a MR for the README.md? There's already a views subheading, which I think we should extend with the info where the class can / should be put.

I think it would be in the image field or in the views style?

Don't think we'll ever be able to add a UI for that while keeping the required flexibility.

TL;DR: Add the class photoswipe-gallery on the view or another dom element around the images you want to group into a gallery.

@anybody Done, pls review.

@thomas.frobieter nice! If possible could you please:
- Use code style for the class snippets
- Eventually add a code example if someone advanced wants to do it code-wise in a template?
- But more important, I think: Additionally to the general explanation, perhaps add the steps a user has to take in the Views UI to add these classes (for less advanced users)

Perhaps @LRWebks can help you with details?
This has low priority, but I think we should help newbies as good as possible.

Perhaps we should generally review the README and check if it explains the general concepts good enough for users starting with PS?

BTW. when using a single image field with the photoswipe formatter, I think these will be grouped, but not for cases where you'd like to have a gallery across fields or view results?

PS: Of course, community help with the documentation is highly appreciated.

Well, I think it's good enough. I won't invest more time into this topic.

Tagging for community help to add the steps to be taken in the View UI to add the classes there. @thomas.frobieter added the required general steps / themer steps.

Here is the required information to add classes to views:

Thanx, @Anybody, you right!

I add class "photoswipe-gallery" to view field - and galleries worked!
