Here's an example. This first photo is what my original photo looked like. The second photo is how it appears if I use Blogger's photo upload feature.


Feel free to click on the photos to see even large versions. The color changes are much more obvious with the full-sized version. Notice the coloring of the second photo is washed out. It's somewhat subtle, but it bugs me enough that I'm now going to start resizing photos myself so I know exactly what will appear on this blog.
