I was recently trying out the attachment control on a form, reading in images as its defaultpicture from disk, until I noticed that with every call to defaultpicture, a mini image was being added to the image gallery where in form design on the ribbon it says "Insert Images".
I ended up doing this 200 times, and removing them all because I thought they looked rather stupid in there (many dozens of repeats).
1) Why does that happen
2) Is there a VBA routine which would dismiss / delete items in that gallery?
