Why Are Images Showing Larger than they Should?

Three images on this page are showing up larger than the CSS specifies. I'm using Chrome 10, and the开发者_JAVA技巧 images are "Subscribe via RSS" "Follow us on Twitter" (both should be 170px but are showing as 200px) {[[RESOLVED]] and "Women who read this also read" should be 780px as the original pic is but is showing at 936px}.

Try pressing Ctrl + 0 (zero) to reset your browser's zoom. The "Women who read this also read" image is 936px wide if zoomed in one level in Chrome.

There is no CSS applied to those images. To avoid issues like this happening, try adding width/height attributes to the img tag itself
