This morning I stumbled across an interesting Outlook question on Quora from a user named Sulong Xu. Sulong Xu asks
How can I view multiple pictures attachments at once in Outlook? Other than one by one, because I want to compare the pictures.
Outlook does not have a built-in means of doing this. It only allows you to view attachments individually. What we need is a solution that presents thumbnail images of all the graphic files attached to a message, something like a digital equivalent to a photographer’s contact sheet. This would allow Sulong Xu to view all the attached images at once. Unlike a contact sheet, the solution would also allow Sulong Xu to click a thumbnail to view the full-sized image. Now, how could we add this capability to Outlook?
