[Plugin: WP-Infobox] Images in the infobox?

How do I insert images (small thumbnails) into the infobox?
Another user (Jagular) had the same problem and then solved it but did not really explain how he did it.

I managed to fix this on my own. All I did was to change the source coude of your infobox plugin so that the item “Label” got renamed to “Image”, and then I changed this througout the whole code, and I then changed the label code to show images with <img> tag.

So how do I “change the label code to show images with <img> tag?

All the best
