This might be a litmus bug. I'm having trouble showing an image if the html code gets long. When I try to put the image at the top of all codes it will show.

I then tried testing on a seperate template where I just repeatedly paste the image and reach around 7000 line of codes. Upon testing the images was showing at the beginning but then its not showing below the page.
I don't know if this is a bug or just a default feature where litmus will just show a blank gray default image if the html code gets too long.

can someone help?
