An approach
in the controller:
function show_image($recordId) {
$this->set('data', $this->Model->findById($recordId));
$this->layout = 'ajax'
}
the view show_image.ctp:
Configure::write('debug', 0);
header("Content-type: image/jpeg"); //assume jpg image
echo $data['Model']['blob_file'];
your view:
echo $html->tag('img', array(
'src' => Router::url(array('controller' => 'your_controller',
'action' => 'show_image', $userInfo['Photo'][0]['id']))
)
);

Besides the size there should be no diff between "binary" and "blob",
I was just thinking that perhaps Cake handled them differently.
I played around with media view and it doesn't seem to be what I'm
looking for.
I have it narrowed down to the headers and I can get the photo to
display but it has to be in it's own view and even then I have to echo
the image directly in the controller action ... this isn't working for
me. I never usually store photos directly to the database but in this
instance i feel it better serves my purpose without taking a hit on
performance.
Ideally I would like to access the image through it's $hasMany assoc
and nest it in an image tag but I'm at a loss for how to pull that off
with Cake.

I've been toying with this one for a while now and I'm not really
getting anywhere.
I'm trying to display a photo stored in db as type "blob". With
conventional PHP I would normally store the photo with type
"binary" and never had any issues ... Blob is not going so well.
I figure the problem has something to do with content type but MVC
is confusing me a bit when it comes to headers or media views. It
seems straightforward enough but I think I'm going about the wrong
way (I'm not using media view or headers at this point).
In my Users Model I set up a $hasMany assoc.
var $hasMany = array(
'Photo' => array(
'className' => 'Photo',
'foreignKey' => 'user_id',
'conditions' => array('Photo.profile' => 1,
'Photo.private' => 0),
'limit' => '1',
'dependent'=> true
)
);
Rendering the photo is the problem.
> View
$html->tag('img', array(
'src' =>
$userInfo['Photo'][0]['file']
)
)
the "file" part of the array is empty:
[Photo] => Array
(
[0] => Array
(
[file] =>
[user_id] => 1
)
)
I tried a lot of different things but nothing worked the way I
want. What is the proper way to go about this?
