how to resize and make the thumbnail view of the photos like in facebook or other sites without distorting the photos

Here is a function that i use which works like a charm for me...

function img_resize($name,$filename,$new_w,$new_h)
{
	$system=explode(".",$name);
	if (preg_match("/jpg|jpeg/",$system[1])){$src_img=imagecreatefromjpeg($name);}
	if (preg_match("/png/",$system[1])){$src_img=imagecreatefrompng($name);}
	if (preg_match("/gif/",$system[1])){$src_img=imagecreatefromgif($name);}
	$old_x=imageSX($src_img);
	$old_y=imageSY($src_img);
 
		if ($old_x > $old_y) 
	{
		$thumb_w=$new_w;
		$thumb_h=$old_y*($new_h/$old_x);
	}
	if ($old_x < $old_y) 
	{
		$thumb_w=$old_x*($new_w/$old_y);
		$thumb_h=$new_h;
	}
	if ($old_x == $old_y) 
	{
		$thumb_w=$new_w;
		$thumb_h=$new_h;
	}
	$dst_img=ImageCreateTrueColor($thumb_w,$thumb_h);
	imagecopyresampled($dst_img,$src_img,0,0,0,0,$thumb_w,$thumb_h,$old_x,$old_y); 
	if (preg_match("/png/",$system[1]))
	{
		imagepng($dst_img,$filename); 
	} elseif (preg_match("/gif/",$system[1])) {
		imagegif($dst_img,$filename);
	} else {
		imagejpeg($dst_img,$filename); 
	}
	imagedestroy($dst_img); 
	imagedestroy($src_img); 
}

Hope this helps..
cheers!!

use this code.

/************Start of main image upload*******************/
		if(is_uploaded_file($_FILES["productimage"]["tmp_name"])!='')
		{
		      $rand_variable=rand(10000,100000);
			  $image_name=$rand_variable.$_FILES["productimage"]["name"];

			if(is_uploaded_file($_FILES["productimage"]["tmp_name"]))
			{
			
				move_uploaded_file($_FILES["productimage"]["tmp_name"], "productimages/" . $image_name);
				
				$Attachments=$image_name;
				
			}
			/************************************Resizing the image ****************/
			$path3="productimages";
			$filetype3=$_FILES["productimage"]["type"];
			$bgim_file_name = $path3."/".$Attachments; 
			$bgimage_attribs = getimagesize($bgim_file_name);
		
			if($filetype3=='image/gif')	
				{
					$bgim_old = imagecreatefromgif($bgim_file_name); 
				}	
			else if(($filetype3=='image/pjpeg') || ($filetype3=='image/jpeg'))	
				{
					 $bgim_old = imagecreatefromjpeg($bgim_file_name);
				}
			  else	if(($filetype3=='image/png') || ($filetype3=='image/x-png'))
				{
					 $bgim_old = imagecreatefrompng($bgim_file_name);
				}
						
			$bgth_max_width = 337; //for Album image
			$bgth_max_height = 337;
			$bgratio = ($bgwidth > $bgheight) ? $bgth_max_width/$bgimage_attribs[0] : $bgth_max_height/$bgimage_attribs[1];
		
			$bgth_width = 337;//$image_attribs[0] * $ratio; 
			$bgth_height = 337;//$image_attribs[1] * $ratio;
		
			$bgim_new = imagecreatetruecolor($bgth_width,$bgth_height); 
			imageantialias($bgim_new,true); 
			$bgth_file_name = "productimages/340X400/$Attachments";
			imagecopyresampled($bgim_new,$bgim_old,0,0,0,0,$bgth_width,$bgth_height, $bgimage_attribs[0], $bgimage_attribs[1]);
			if($filetype3=='image/gif')	
				{
				    imagegif($bgim_new,$bgth_file_name,100);
					//$bgim_old = imagegif($bgim_file_name); 
				}	
			else if(($filetype3=='image/pjpeg') || ($filetype3=='image/jpeg'))	
				{
					 imagejpeg($bgim_new,$bgth_file_name,100);
				}
			  else	if(($filetype3=='image/png') || ($filetype3=='image/x-png'))
				{
					 imagepng($bgim_new,$bgth_file_name,100);
				}				
			/************End Resize *******************/
