Selectors - how to make them work !?!, examples dont help

Hello. i have spent that last few days trying to figure out how to create a basic user selector and it is proving to be ridiculously frustrating. i am using latest sitefinity (5.x).

i have gone though this example: 
http://www.sitefinity.com/documentation/documentationarticles/developers-guide/how-to/how-to-create-a-simple-image-selector 
but cannot even get this to work.  when i try it, instead of a list of my images all i get is a label with "Title", as shown in the image.

i need to setup a control similar to when adding users to a role where i can select from a list of users.  

any suggestions on how to get this sitefinity example?  Are there more steps that they just didn't bother to explain about on the example?

Hello Rory,

Thank you for contacting us about your issue. The post that you were folowing was updated. Here you can see the updated post and folow the instructions there (pay attention to the Installation Instructions at the bottom). Also I recommend you to folow this video which visually explains all the steps (I think it will help you solve your problem faster).

Still, if you did all the steps in the post you were following, the only thing you should do is to slightly tweak your simpleimageselector:
    1. Go to your page and click "Edit" on the simpleimageselector;
    2. Go to "List Settings" and under the "List template" field/(dropdown menu) click "Edit selected template";
    3. Paste the folowing markup under the other declarations of the same type:      

Hi Ivan.  thanks for the reply.  i had gone through those examples as well.   i did get this example working so am making progress now. http://www.sitefinity.com/blogs/radoslavgeorgiev/posts/12-02-27/creating_one_to_many_relationships_in_dynamic_modules.aspx
