[Plugin: EsAudioPlayer] Custom button images

Firstly, this is a fantastic plugin, thank you. I’d love to be able to use this, however I need to have a custom play and stop image. I can’t use the image id method to replace the buttons, as I need multiple posts on a category page to all have a sound file. For the image button method, each image needs to have their own id, however I can’t do this as the client needs to be able to update her own pages without having to edit any code.

Any idea how I could get around this?

Thanks in advance
