I have the same issue here: gallery (PW: deek)
All the solutions I've found have involved using Code Injection, which is only available for Business plans.
I'm working for a client who doesn't need any other function from a business plan, and I'm not going to push them to upgrade just for this.
Right now my options are:
1. go back to 7.0 (I really, really prefer working with 7.1. and 7.0's options aren't that great either)
2. add each image individually and form a kind of masonry grid with organizing & spacers in the hopes that SS will update the lightbox caption options before I need to add more images (will probably be a stupid amount of work and I'm worried about responsiveness - a lot of iPads being used in the target audience)
Is there any other option? Or, is there an idea of when Squarespace might include this function?
