Administer nodes required to view all comments in View - Block

Let me set out my problem right:

1. I have created a content type (image)
2. I have created a new view, with a block display, in which i load all comments posted to the specific node.
3. I have created a context, which shows the block on a page (custom page with custom view)

So far so good and everything works as expected for the admin. But, for an Authenticated User con the node page, EVERY comment is displayed but not every comment is loaded in the block on the custom page. The user can only see SOME comments made on the image content type...

When i give the Authenticated User role permission to 'administer nodes', every comment IS loaded, so that is working. But i don't want the permission turned on (since they can now edit each and every content type created by anyone).

p.s. the Authenticated User has the right permissions for the image content type... (create content, and edit own content)

Can anyone help me out since this is driving me crazy!
