I just used this image in a question, and I think you'll agree that it would look much better if the image was lowered a bit. I tried the html code
<img src="http://mathurl.com/332t642.png" style="vertical-align:-5px">
but this didn't work: The image just didn't show up. (The 5 pixel adjustment I obtained by testing in a separate html file.) Is there another way to vertically align the image?
