Vertical align png image

The png image is showing up a few points below the rest of the line of text. How can I raise it so as to make the line look completely even?

I have tried using variants of vertical-align in my theme stylesheet but it is not having any effect. Here’s an example:

.cryptxImage {

	vertical-align: +3px;
}
