Email images as pdf attachments

I have a Workflow Behavior setup with the basic Attachment Template Google Doc containing this: <<Start: [Pictures]>><<[AttachmentUrl]>><>

It used to place the AttachmentUrl images on their own pages in the Google Doc with only a small white border. Now, the images are only 1/4 the page and sometimes multiple images get tiled on one page.

It seemed to start when we upgraded our “Image upload size” from Medium to Large which doesn’t really make sense to me.

I tried setting up a Format Rule for attachments and that didn’t work. I tried putting <<Start: [Pictures]>><<[AttachmentUrl]>><> in a 1x1 table that filled the whole page and that didn’t work either.

It’s almost like AppSheet is using a Thumbnail to fill the Google Doc instead of the full image size. Any ideas?
