You probably wanna look at http://www.slowcop.com/ http://www.slowcop.com/ (which was at the front of HN today), which largely suggests what others have said so far...link to jquery on google, fix missing Cache-Control: Public headers, gzip/minify/merge css/js...add far reaching expiry headers... 0.10 to 0.15$ per GB is pretty standard low-end for low bandwidth sites. Prices only really drop once you cross the 50-100TB/m range. Your problem is that you're hosting cost (linode) is something you need to pay regardless, so you want to use that "free" bandwidth. I've seen people swap domains. Have images1.mysite.com which points to their main servers...and then when they get near their limit they switch to images2.mysite.com which would point to a place with cheaper bandwidth. Problem is, linode prices are pretty damn reasonable (probably cheaper than S3 when you add storage/GETs/etc). If you prepay at linode it's $0.10/gb...you should just buy a Linode 512 at that point, since it's the $20/200gb ($0.10/gb again) + you get the extra machine. 100tb.com, a softlayer reseller, is a known large-bandwidth [over]seller. They have VPs for ~$100/month with 10TB included..there may be other options, but I probably wouldn't recommend this route. I hope you are making backups of your images...
