How to optimize the bandwidth for a wallpaper site?

[webhmonster]

This is a forum about network, then i hope to get quick answer.
I have a site about free HD animal wallpaper, and free landscape wallpaper . But it costs about 900G each month, nearly hit the 1T limit of the vps. i would like to find a way to reduce the bandwidth cost, but will not reduce the daily visitor. any one have a good way? I hope to reduce the traffic costs, but not affect the current google index and SEO.

Any expert has good suggestion?

Look for a less expensive ISP.

Compress the thumbnails with higher level jpg compression, do a slight compression increase on the actual wallpapers. I understand you dont want to lower quality, but there isnt a ton that can be done without sacrificing some quality for the images.

use small thumbnails, put the actual wallpapers into compressed archives, like zip or rar?

Only downside to this is most image formats do not do lossless compression very well. You might save a few kb, but the time spend re-linking/compressing them to begin with might not pay off.

Far easier to just turn on HTTP gzip / deflate.

True, but this bumps the performance requirements up a bit, i wonder if this might not be an issue as well.
