I could use yousendit.com instead for the large attachment. This is the total size though, not the compressed size (which might not be that different as PNG images don't compress well). I'm just wondering if you can handle an extra 8 MB on your server or webhost. Webhosts usually have like 200 MB on the cheap end and 8 MB is quite a punch on that (4% of the total). Good webhosts give like 6000 MB of disk space - 8 MB on this is not really noticeable.

I'll split the document up in a way that seems decent. The minimum will be 5 pages, my target is around 10 pages.
