Image stacks such as for CTs and MRIs can be created by choosing "Edit source" and adding for example the following code (resultant stack displayed at right):
<nowiki>{{Imagestack</nowiki><br>|width=250<br>|title=<br>|align=right<br>|background=#ffffff<br>|loop=no<br>|File:Computed tomography of human brain (16).png|<br>|File:Computed tomography of human brain (15).png|<br>|File:Computed tomography of human brain (14).png|<br><nowiki>}}</nowiki>
To move through the images, hover over the image and use scroll wheel, drag the mouse over the image, or click the < or the > above each stack. This functionality should activate when the page is fully loaded, which may take some time.
