How to display Image in grid

Write this code in Grid.php:-

$this->addColumn("data", array(
"header" => Mage::helper("userdesign")->__("Design"),
"index" => "image",
'align'     =>'center',
'renderer'  => 'userdesign/Adminhtml_Userdesign_Renderer_Image'
));

Then make a "Renderer" folder in module( location - Grid.php)
In Renderer Make a PHP file , Named Image.php
and put this code

<?php
class Userdesign_Userdesign_Block_Adminhtml_Userdesign_Renderer_Image extends Mage_Adminhtml_Block_Widget_Grid_Column_Renderer_Abstract{
     
    public function render(Varien_Object $row)
    {
$designUrl=Mage::getBaseUrl('web').'design/designs/';
        $html = '<img width="75" height="75" ';
         $value = $row->getData('designId');
      $html.= 'src="' . Mage::getBaseUrl('web').'design/designs/'.$value. '_1.png"';
        //$html .= 'src="' . Mage::getBaseUrl('media').$row->getData($this->getColumn()->getIndex()) . '"';
        $html .= 'class="grid-image ' . $this->getColumn()->getInlineCss() . '"/>';
      //  $html .= '<br/><p>'.$row->getData($this->getColumn()->getIndex()).'</p>';
        return $html;
    }
}
?>

 Change your Module Name and image path accordingly..

CodeIgniter Disallowed Key Characters

Open libraries/Input.php (system/core/Input.php in CI version 2.0+) and locate function _clean_input_keys($str){, The whole block should look like so: function _clean_input_keys($str) {     if ( ! preg_match("/^[a-z0-9:_\/-]+$/i", $str))     {         exit('Disallowed Key Characters.');     }     return $str; } Modify the PCRE sot that it allows the new chars. Please not that the char thats missing is the .(dot) and you should always escape the .(dot) in Regular Expressions as they will otherwise allow any single char. /^[a-z0-9:_\/-\.]+$/i
