How would TIMTHUMB.PHP affect the SEO of a website, or Image SEO

If I use timthumb.php for reducing images and posting them automatically with the appropiate size on my website sounds fantastic. Saves a lot of work.But would that affect the results in http://images.google.com ?Let's say I have a photo named "my-dalmatian-dog.jpg" and then I apply tinthumb.php..it would be changed to some other name...and I dont know if the search results would be that great.what would be the result of using this, in terms of SEO ?
