Man, the compression for Jpegs sucks on blogger. I'm going to look into other formats or hosting these images elsewhere.
Much better! I've had this issue with other websites where, for one reason or another, they just don't play as well with JPEGs as they do with PNGs. Of course, the file size of a PNG is about double that of a JPEG, but when the whole point of this site is the images I can live with an extra 800kb per image!
So, I've converted all of the images in the blog posts and the Gallery page into PNGs. The JPEGs were drastically throwing off the color quality of the images too. They look so much better now.
As always, let me know if you have any feedback.
