Picking image from server: FileField_Sources not working
I just found the answer myself.

If anyone else would come into the need for something like this:


Download the 3 modules that I had typed in my question
Go to the Manage fields of your content type &amp; click edit next to the Field
Scroll down and click Allow users to select files from IMCE File Browser for this field.


I forgot 2 &amp; 3 :)

I do have to say that it's not 100% what I wanted, as I have different image fields in different nodes, and it only finds the image fields of the nodes that it's in. But I guess I should have used the references instead to make that work...

If anyone still has an answer for my secondary question, it would be much appreciated though, but I'll try to fix that myself tomorrow.
