Yes it could be run multiple times.
Although I am not to sure if that will help in your case.

What is the extension of the image?

The extension is .jpg.
Strange thing when I am changing host, then i can't run fix_attachments-thumb.php on my new host space, i got always an empty page.
What did i do wrong? THank you!
Thank you!
