Hi!

I'd the same problem, just replace the tcpdf/include/tcpdf_static.php function file_exists (L1879 in tcpdf 6.3.4) like this:

public static function file_exists($filename) {

if (preg_match('|^https?://|', $filename) == 1) {
    return self::url_exists($filename);
} 

if(stripos($filename,'data:')===0) {
    return true;
}

if (strpos($filename, '://')) {
      return false; // only support http and https wrappers for security reasons
}

return @file_exists($filename);

}

Version 6.2.21 works fine in local and server. I have 6.3.2 and render Ok in local and not works in server. Above solution not working for me. I checked with 6.3.2 and 6.4.4

Do this <img src="@/9j/4AAQ.... instead of <img src="data:image/png;base64,/9j/4AAQ....

@detook solution works, but so is @LittleBigFox's if one is ok with modifying the static file.

I personally find it very sad that we have to add an @ instead of the default:

data:image/png;base64

I've created a PR with @LittleBigFox's fix: https://github.com/tecnickcom/TCPDF/pull/671
