Images and Custom Fields, Tags

I practically broke my arm patting myself on the back for figuring out how to implement a “Currently Listening to…” field via custom tags. I also cleverly (so I thought) edited the stylesheet so that it would place a .gif image of a music note on the same line with the output.

To my horror I see that the image appears in every instance where I’ve used the custom tag, not just the “Currently Listening” (see my “Scary Stories” category and check the movie reviews and the Votio plugin, you’ll see what I mean).

Is there some way to make these separate? I suspect not, since there’s only one output tag. I don’t know enough about PHP to figure out how to make the image conditional.

Thanks!
