After seeing the Pizza Express examples of pixel art and listening to Mike Regan's presentation here - http://www.emaildesignreview.com/email-design-inspiration/video-future-of-email-london-2015-2647/

I saw some value in slicing our logo and using the pixel art method to add some branding with the images off.

Althought I think it looks pretty good it seems to take a while for the images to download in Outlook 2007 etc. I remember reading somewhere about Outlook only downloading the images in batches? Does anyone know why this happens and if there's away around it. For me it takes too long to download all the images so instead of the pixal art I'd prefer the other images downloaded quicker.
