[code=php]
 here's a php function that that I made, it will except PNG, GIF and JPEG/JPG file formats and will export to a JPEG/JPG. 
 
 <?php
 //Creat Function: resize photo and save
 function resize_photo_save($sourcefile, $destfile, $max_width = '', $max_height = '', $quality = '90')
 {
 //get image size
 $size = getimagesize($sourcefile);
 
  $width = $size[0];
  $height = $size[1];
 
  //set new size vars
  $new_width = $width;
  $new_height = $height;
 
  //check width size
  if($max_width)
   {
   if($new_width>$max_width)
   {
   $percent = $max_width / $new_width;
   $new_height = $new_height * $percent;
   $new_width = $max_width;
   }
   }
 
  //check height size
  if($max_height)
   {
   if($new_height>$max_height)
   {
   $percent = $max_height / $new_height;
   $new_height = $max_height;
   $new_width = $new_width * $percent;
   }
   }
 
  //round width and height to nerest whole number
  $new_width = round($new_width);
  $new_height = round($new_height);
 
  //determin image type
  $image_type = exif_imagetype($sourcefile);
 
  if($image_type=='1')
   {
   $img_src = imagecreatefromgif( $sourcefile );
   }
 
  if($image_type=='2')
   {
   $img_src = imagecreatefromjpeg( $sourcefile );
   }
 
  if($image_type=='3')
   {
   $img_src = imagecreatefrompng( $sourcefile );
   }
 
  //check for valid image type
  if(!$img_src)
   {
   return '0';
   }
  else
   {
   //create new image, resample old image, save new image and destroy all temp files
   $img_dst = imagecreatetruecolor( $new_width, $new_height);
   imagecopyresampled($img_dst, $img_src, 0, 0, 0, 0, $new_width, $new_height, $width, $height);
   if(!imagejpeg($img_dst, $destfile, $quality))
   {
   return '0';
   }
   else
   {
   return '1';
   }
   imagedestroy($img_src);
   imagedestroy($img_dst);
   }
  }
 
 ?>
