file_exists() function is quite slow.
in your case, better do fopen() to check if the file exist,
because you gonna do fopen() anyway if the file exist.
if fopen() return error, then you can assume the file does not exist.
dont forget to add "@" in front of the function name, to surpress err

if ($f = @fopen($image)) {
  // file exist, read the content, then echo to browser
else {
  // file does not exist, open default image
