The filmstrip is a great feature to use to share a collection of images. However, currently you can only provide on caption for the entire collection of images. For example, to tell a story with a series of images from beginning to end, it would be helpful to provide a small description of each image in the filmstrip with the caption below as this is designed (as opposed to the obstruction of the images with the slideshow option).
In our case, we are showing historical photos of fire engine crews over a series of years. It would be great to further explain the addition of apparatus, changes in crews and ranks, and events that took place.
