I have an image of my vCard QR code on my iPhone. When I want to show it so it can be scanned, I have to open Camera Roll, pick the album it's in, then select the image (it's the only one in that album) before I can show it.

Is there a way to make a shortcut on the iPhone desktop directly to that image to speed this up? For example, on my iMac, the .jpg extension is associated with Preview: I click on a .jpg, Preview opens and displays the image. Surely this is possible in the iOS.

I'm sure folks who want to show that picture of their grandchild, significant other, new boat, etc. etc. would appreciate this, too.
