Please click on the “Add Media” button above the listing description editor, you can upload multiple images and re-order them with drag and drop in the same way. Then you can select the main image in the right sidebar.
Hi ihor, I think vheo is right about this. The image gallery management is not intuitive at all. I believe it would be better to give it its own metabox in an upcoming iteration.
Right now if I follow your instructions here, the nice-looking gallery with multiple images is created on the listing front end at the top, but then the images are displayed in the description area as well, and those don’t look too great.
Thanks for your suggestion, I agree that its not intuitive and I’ll try to implement the same UX for the front-end and back-end, but I’ll stick to WordPress dashboard UX for now. If you upload images via back-end please don’t click “Insert gallery” button, if you upload images and just close the modal they will be displayed anyway.
