We have a snippet type available which will allow users to crop a small section of an image and place that cropped image onto a web page.  When a contact clicks on the image the small crop pops up into the full image.

This is useful because it allows the small image to be expanded to a recognisable size.

Example:

Use an image of a building

Using the Lightbox feature, create a crop of just the front door

The small front door crop expands to the full snippet size on the web page, making it recognisable as a door

When the web visitor clicks on the front door image the picture pops up back to the full building image

Images in this feature can be viewed in a "carousel" style, one after another.
