I have had consistent problems with pasting images into Gmail. I use Firefox (just in case that is relevant, but I wouldn't expect so). The image displays fine as I write it. But when it arrives at my family members Gmail account, it is being displayed in some base64 encoded form as many pages of text with a beginning like:

img src="data:image/png;base64,iVBORw0KGgoAAA.....

On the receiving end I cannot get the images to display properly.

Are you using Snagit as well?!topic/gmail/hpV05eNkKHI – Bon Gart Dec 18 '12 at 23:07

Seems to be an issue with Firefox and the compose tool. If I compose in Chrome, I can view it in Chrome or Firefox. If I compose in Firefox, it replicates the above symptoms whether I read in Chrome or Firefox.
