Have you ever seen spacing in between where you email's graphic was sliced up? I first noticed a space in between two images on iphone 5 preview. I made a few quick adjustments and re-tested--space when away. Then, about an hour later i re-ran the test with the same html, and the space in between the images displayed again! I refreshed, the space disappeared. Refreshed AGAIN, space reappeared. I cant tell if this is a coding issue or slow loading with litmus. Has anyone else experienced this issue? I sent my html to an ACTUAL iphone 5 and the space dissappeared.
