Hello again! Chris recently emailed me with a comment, my script doesn’t scan sub-directories and fix the issue as well. Sorry about this, I could add this in but the next version of wp is bound to fix this highlighted problem and sadly I do not have enough time. Instead, please just drag the script in the sub-directories and run it from there.

There is a file you can download from my website that fixes the problem: WordPress Eats Thumbnails

This is what you need to do to get permission back, create a file called whatever-you-want.php in the same folder as all the thumbnails and copy this code into it:

<?php
// Note that !== did not exist until 4.0.0-RC2

if ($handle = opendir('./')) {
    echo "Directory handle: $handle\n";
    echo "Files:\n";

    /* This is the correct way to loop over the directory. */
    while (false !== ($file = readdir($handle))) {
        if(chmod($file, 0755)) echo "\n".$file." - CHMOD to 0755 a success<br/>";
        else echo "\n".$file." - CHMOD to 0755 a failiure<br/>";
    }

    closedir($handle);
}
?>

It’s a bit of a fudge but it works! I just wrote it, change 0755 to whatever permissions you want to set. Good luck!
