Big THANKS to you UncleCheese. After a little trial and error and guidance from you (tried my best not to ask you for more help) I finally figured it out.

Here is the final code for the basics of what I've been trying to do. This currently works but if there is something messy that I should probably clean up please advise. I'm a designer not a developer and Silverstripe has been a great experience. I hope this helps others out there :)

ProfilePage.php

<?php

class ProfilePage extends Page {
   
   static $has_many = array(
      'PhotoSets' => 'PhotoSet'
   );
   
   function getCMSFields() {
      $fields = parent::getCMSFields();
      
      $photosetfield = new DataObjectManager(
         $this,
         'PhotoSets',
         'PhotoSet',
         array(
            'PhotoSetTitle' => 'PhotoSetTitle'
         )
      );
      $photosetfield->setAddTitle('Photo Set');
      $fields->addFieldToTab('Root.Content.PhotoSets', $photosetfield);
      
      return $fields;

   }
}

class ProfilePage_Controller extends Page_Controller {}

?>

PhotoSet.php

<?php

class PhotoSet extends DataObject {
   
   static $db = array(
      'PhotoSetTitle' => 'Varchar(255)'
   );
   
   static $has_one = array(
      'ProfilePage' => 'ProfilePage'
   );
   
   static $has_many = array(
      'Photos' => 'Photo'
   );
   
   public function getCMSFields()   {
      return new FieldSet(
         new TextField('PhotoSetTitle'),
         new FileDataObjectManager(
            $this,
            'Photos',
            'Photo',
            'Attachment',
            array(
               'PhotoCaption' => 'PhotoCaption'
            )
         )
      );
   }
}

?>

Photo.php

<?php

class Photo extends DataObject {
   static $db = array(
      'PhotoCaption' => 'Varchar(255)'
   );
   
   static $has_one = array(
      'Attachment' => 'File',
      'PhotoSet' => 'PhotoSet'
   );
   
   public function getCMSFields()   {
      return new FieldSet(
         new TextField('PhotoCaption'),
         new FileIFrameField('Attachment')
      );
   }

}

?>

ProfilePage.ss

$Content

<% if PhotoSets %>
   <% control PhotoSets %>
      $PhotoSetTitle
      <% control Photos %>
         $Attachment
         $PhotoCaption
      <% end_control %>
   <% end_control %>
<% end_if %>

Same situation, different problem:

I have Project Pages, which can have assigned one Mentor, and multpile Participants as DataObjects.
Each Mentor,Participant have multiple images.
Almost similar to posts above, just i'm using HasOneDOM and HasManyDOM

Geting error:

[User Error] Couldn't run query: SELECT "Participant"."ClassName", "Participant"."Created", "Participant"."LastEdited", "Participant"."FullName", "Participant"."PictureID", "Participant"."ID", CASE WHEN "Participant"."ClassName" IS NOT NULL THEN "Participant"."ClassName" ELSE 'Participant' END AS "RecordClassName" FROM "Participant" WHERE ("" = '7') ORDER BY Created DESC Unknown column '' in 'where clause'

It somehow doesn't make relations Participant=>something?

==========Project Page============

class Project extends Page
{
static $has_one = array (
'Mentor' => 'Mentor'
);
static $has_many = array (
'Participants' => 'Participant'
);

function getCMSFields()
{
$fields = parent::getCMSFields();

$participants = new HasManyDataObjectManager(
$this,
'Participants',
'Participant',
array(
'FullName'=>'FullName'
)
);

$mentor = new HasOneDataObjectManager(
$this,
'Mentor',
'Mentor',
array(
'FullName'=>'FullName'
)
);

$fields->addFieldToTab('Root.Content.Mentor', $mentor);
$fields->addFieldToTab('Root.Content.Participants', $participants);
return $fields;
}
}


========== End Project Page============

==========Participant Page============

class Participant extends DataObject
{
static $db = array (
'FullName' => 'Text'
);

static $has_one = array(
'Picture'=>'ImageResource'
);

static $has_many = array (
'Projects' => 'Project',
'Images' => 'ImageResource'
);
public function getCMSFields()
{
return new FieldSet(
new TextField('FullName'),
new SimpleImageField('Picture'),
new FileDataObjectManager(
$this,
'Images',
'ImageResource',
'Attachment',
array(
'Description'=>'Description'
)
)
);
}
}


==========End Participant Page============

==========Mentor Page============
Same as Participant
==========End Mentor Page============

==========ImageResourcePage Page============

class ImageResource extends DataObject {
static $db = array(
'Description'=>'Text'
;
static $has_one = array(
'Attachment'=>'Image',
'Mentor'=>'Mentor',
'Participant'=>'Participant'
);
public function getCMSFields() {
return new FieldSet(
new TextField('Description'),
new FileIFrameField('Attachment')
);
}
}

==========End ImageResourcePage Page============

Totaly lost in space...
