Animated pictures?

Question

PHP

As many on the forums write, animated pictures in jpg format are obtained by simply changing their name from gif.

Answer 1

It's better to use the exif_imagetype() function . If there is no access to install PHP modules, then here is a universal solution:

function getRealMimeType($filename) {
  $mimetype = false;
  if (function_exists('finfo_fopen')) {
    $mimetype = finfo_fopen($filename);
  } elseif (function_exists('getimagesize')) {
    $mimetype = getimagesize($filename);
  } elseif (function_exists('exif_imagetype')) {
    $mimetype = exif_imagetype($filename);
  } elseif (function_exists('mime_content_type')) {
    $mimetype = mime_content_type($filename);
  }
  return $mimetype;
}

Answer 2

get exif from gif and if frame > 1 then don't skip
