improve image selection usability

I suggested just nid entry - simple form as this is the simplest thing.
Just to replace the list with form...
Of course it would be better to make some included filters like image_assist and choose pictures by clicking but I know it make take a lot of time. That's way I just asked for this little but really helpfull thing like changing list in a form.

Selector based on taxonomy I may do by myself using views. So just form entry needed...

However drupal 7 release won't support this I think D6 will last a long time. New D7 won't have support of many module, that's way many people will use D6. Even D6 does not have many helpfull modules that You can find in D5.

Thanks for answear... Maybe someone will notice this and make some little patch...

I've tried to place additional codes:
[in line 219 function image_attach_form_alter(&$form, $form_state, $form_id) of image_attach.module]

	$form['image_attach']['iids'] = array(
          '#type' => 'select',
          $value => empty($node->iids) ? NULL : $node->iids,
          '#multiple' => TRUE,
          '#size' => 6,
          // Title, options and description are set just below.
        );
//my own input field to place chosen iid number
		$form['image_attach']['chosen_iid']=array(
          '#type' => 'textfield',
          '#title' => t('Index fotki'),
          $value => '',
          '#description' => t('Wstaw znaleziony index fotki.')
        );

and additional in function image_attach_image_add_submit(&$form, &$form_state):

  $c_iid=$form_state['values']['chosen_iid'];
  if(isset($c_iid) && is_int($c_iid) && $c_iid>0){
     db_query("DELETE FROM {image_attach} WHERE nid = %d", $form['nid']['#value']);
     db_query("INSERT INTO {image_attach} (nid, iid, weight) VALUES (%d, %d, %d)", $form['nid']['#value'], $c_iid, -1);
  }

but this is not working - nothing happends, image with c_iid NID entered in the input field is not submitted... of course without this ?php? marks - just put here to mark keywords

I do not really see how to solve this... but I want to open my news-site soon... So please help me.
It's complecated to get know wher and how these all variables and arguments are passed... Just want to add additional input entry that will take NID (image node id) and insert the image into article body the same way as select list (after preview or submit button clicked).
[Would be nice if after refreshing/validation form the input field was felt in with the number recently inserted]
I've already lost 2 days searching how it work bu I'm not really good programmer, espacially not php which seems like freestyle programming...

Ok I was looking around making some changes and undoing... And I didn't manage to do this.
But I've found probably a bug beetween workflow and image_attach (I'm not sure this wasn't mebecause I was makeing some changes... but 80% not me :-)

When adding image using image attach everything is ok (so my changes were no destructive). After all image is added and in preview article looks fine. However after workflow state change - image added with image_attach are erased...

I tried this with 2 roles I created. Editing post does not erase image. But state change does. I tried if some permissions don't just hide image but there are no permissions about visibility of image attached with image attach...
I also use lightbox2... it handles the image too... so maybe it's lightbox issue?

However if someone could check if workflow state change erase image node from article this might be helpfull to others.
I probalby will try other modules now...

Workflow state change I mean I make w workflow with different roles, and if someone changes article state form example state "preparing" to example state "revision". I mean using workflow module. Ok I'll report this bug.
