So, can I deliver banner files gzipped? I have an ad that we converted with Swiffy; it looks amazing, and right there, in the Swiffy output window, it shows the file size of the banner as 88k -- but it's the gzipped file size. The raw file size of the html when I download it, is 346k.
I'm pretty sure I can use gzipped files in Doubleclick, but what about other media people/publishers? Anyone have experience with this?
