Organizing Gallery Images

I am going to try to keep this as short as possible, but it won’t be, sorry. The web developer who was hired to create our website is no longer working in the field and we do not know anyone else that uses WordPress so I am hoping someone here can help us.

our site is https://www.crewsinc.net

We have 293 galleries, 361 pages and almost 19,000 images – with more to add continually. Each gallery has on average 40-80 pictures.

It used to be that when you created a gallery, the uploaded images were displayed on the ‘Edit Gallery’ page and that is where they could be dragged/dropped for organization. Now when you go to the gallery, the images are not displayed. We are not sure what happened but now if you want to manipulate the images in a gallery, on the gallery page you have to hit ‘add new’ by Gallery Images, then go to the gallery tab. The images are shown here but they are very small and the option to do a ‘Bulk Action’ like delete is not available. We need to be able to quickly edit the images as needed so going to the media library and searching is not really effective for our needs.

We have never felt that WordPress was user friendly when it comes to organizing images on galleries, the drag/drop method is time consuming and tedious. The sort ordering has never worked no matter what we have tried.

I downloaded the photo gallery plug in but I am not sure how we attach pages to the galleries created with it.

Can anyone advise on plugins or settings that would help us with organizing images?

Does anyone know if we changed something in our account that changed the original gallery display?
