Image in trigger not displaying

Hi,

I’m trying to use an image (png or jpeg) as the trigger for the hide-show text. The drop down arrow is appearing, and I can type text instead and the trigger does work. BUT the image is simply not displaying at all.

Any ideas what I’m doing wrong here? I followed the documentation, this is what I’m putting in.

[expand title=”<img src=’image_url_is_here’ />” tag=”div”]

the text that appears is written here[/expand]

Thanks for your help!!
