I'm using Andrea's photo here as an example, but this post is for all of you. Make sure you edit your photos before you post them on your blog. Make them as professional-looking as possible. This means nothing around the image--no carpet, no wall, nothing. Make sure they are in focus and the exposure and contrast are adjusted to the right levels.
All this takes just a few minutes in photoshop or other online photo editing services--even preview.
Here are before and after shots of one of Andrea's expression studies.
