put this in your app helper:
/**
* display image tag from blob content
* enhancement for HtmlHelper
* 2010-11-22 ms
*/
function imageFromBlob($text, $options = array()) {
//<img alt="" src="data:image/png;base64,' .
$this->_getBase64() .
'" /><br/>
$text = 'data:image/png;base64,' . base64_encode($text);
$image = sprintf($this->tags['image'], $text, $this-
>_parseAttributes($options, null, '', ' '));
return $image;
}
$this->Html->imageFromBlob($blob);
