$thumb code

[Gio~Logist]

Is it possible to use the code below... in addition to other codes perhaps, in order to create a thumbnail for profile pics?

PHP Code:

            // create thumbnail (nop) x=height y=width
            $size_y = imagesy($thumb['file']);
            $size_x = imagesx($thumb['file']);
            $width = 100;
            $height = 100;
            $thumb['height'] = ($size_y / $size_x) * $width; 
            $thumb['data'] = imagecreatetruecolor($width,$thumb['height']); 
            imagecopyresampled($thumb['data'],$thumb['file'],0,0,0,0,$width,$thumb['height'],$size_x,$size_y);            
            
            // capture new thumbnail image for storage
            // all thumbs will be jpg format
            ob_start();
                imagejpeg($thumb['data'],'',75);                
                $thumbdata = ob_get_contents();
            ob_end_clean();

            // clean up GD
            imagedestroy ($thumb['data']); 
                
            // add watermark if enabled (nop)
            if( $vbg_use_wm )
            {
                // get watermark file 
                $wm_filename = $vbg_path . $vbg_wm;
                
                if( file_exists( $wm_filename )) 
                {
                    $wm_size = getimagesize($wm_filename);
                    
                    if( $wm_size[2] == 3 && $wm_size != false)
                    {
                        $wm = @imagecreatefrompng($wm_filename);  
                
                        // get demensions
                        $wmw = $wm_size[0];  
                        $wmh = $wm_size[1];
                
                        // center WM in image
                        $dest_x = ($size_x - $wmw) - round((($size_x/2)-($wmw/2))); 
                        
                        // set top or bottom
                        if( !$vbg_position )
                            $dest_y = 5; 
                        else
                            $dest_y = ($size_y - $wmh ) - 5;
                            
                                // merge the images
                                imagecopymerge($thumb['file'], $wm, $dest_x, $dest_y, 0, 0, $wmw, $wmh, 100); 
                            
                                // clean up GD
                                imagedestroy($wm);
                    }
                        }
            }

                       // capture image
                       ob_start();
                switch ($imagesize[2]) 
                {
                    case 2:
                        imagejpeg($thumb['file'],'' ,75);
                        break;
                    case 1:
                        imagegif($thumb['file']);
                        break;
                    case 3:
                        imagepng($thumb['file']);                
                        break;
                }
                $data = ob_get_contents();    
            ob_end_clean();                 
            
                    
            // clean up GD
            imagedestroy ($thumb['file']);
