Chiming in late to say that, similar to Luke, at Barnard we created have created a very simple exhibit platform using Drupal content types--basically we have an "exhibit" content type node that contains "exhibit object" content type nodes in a given order. The exhibit content type has fields for a title, thumbnail, and brief description, while the exhibit objects have fields for a title, description, and theme (which are optional but are used to create structured sections within the exhibit). Then you can drop in unlimited images (at this point you just upload a small-ish jpg) which themselves have fields for captions and PIDs, to auto-generate a link to whatever object you want in the collection. If you have any questions, feel free to email me and I'll put you in touch with the developer who created this.
Here's an example of an exhibit we made with this [1], and here's some relevant code on our github [2]. I'll note that it needs some work and it doesn't interact very much with the actual objects in the Islandora repository, beyond that auto-generated link from the PID. Also, for more complex DH projects we'd likely use a different tool or platform and embed it in our site.
