I just sent a test to my Gmail account, the email is all images (currenty) with just an unsubscribe link as text.

I have images on by default and most emails do show the images as expected but this test I sent doesn't.

When I add a block of Lorum ipsum they do show as default again.

I'm going to do some more testing to try and work out the word/character limit they require but has anyone else seen this happening? Any other testing already done?

N.B Text is being added to this email is just part of a test while I'm waiting for the extra copy.
