Please re-read my code:

if (size changed) { // any size change, means content change
  make new image
} else {
  if (mtime changed) { // mtime change, could mean content change
    // make md5 test only, if mtime is not enough for you
    if (noContentCheckFlag set || content changed)
       make new image

That is I make a shortcut if the size has changed.

I didd't bring up the mtime subject. For me a changed mtime is enough. It was the folks with the FTP
server setup, etc who didn't trust it. Fine with me.
