[Typo3] editIcon - How to make own image editable?

[Yomo]

Hi,

For one of my pages I've made an extension template with 5 images on it.

Because I've made my own content for that page via TS (and not via the 
Pagemodule), my content isn't editable by default. To enable the 
editIcons I've added the following line to my code.

temp.thiscontent.1 = COA
temp.thiscontent.1 {
   10 = IMAGE
   10 {
      file = fileadmin/user_upload/images/myimage.jpg
      file.maxW = 137
      linkWrap = <a href="index.php?id=11&country=holland"> | </a>
      stdWrap.editIcons = 1
   }
}


However, the problem is that I can click on the editIcon, but I can't 
see the image in the Typoform, nor can I change it (and that's of course 
what I want to do!).

Please help!

Regards,
Yomo
