Images are not displaying at all for me in Outlook.com for one particular email. I tried sending a past email to Outlook.com and this worked just fine - any ideas as to why images wont display? I am stumped! The size of the html is 10 KB. Is that too large? There is one animated GIF. All other images are JPEG's. Is there a different format i should be using for images?

Here's an example of code i have around each image:
