Stacks are a set of sequential images that can be scrolled. To create a stack simply zip the images and upload the zip file instead of the individual images.
Take care to make sure the images are sequentially numbered, preferably with leading zeros (although this is not mandatory) as follows:
It is worth keeping in mind that the first image within a stack is used as the thumbnail image by default, and that often this will not be a good representation of the pathology. It is often helpful to, after saving the case, select a different key image.
Just as with single images if no caption is provided it inherits the title of the case.
Each stack can have a description, and modality and (where appropriate) a sequence / contrast phase.
