Auto Insert Alt Tags To Images On Wordpress

My Magento site has 5,000 images; some with alt tags and some without.

Does anyone know an extension that can automatically update the images with an alt tag from the image name, image post, etc. Whatever works to auto pull the image data into the alt tag.

Thanks!

I see there are quite a few such plugins out there. Never used them personally.

Sounds like a great idea though, if you find the right one it should be a big help to your site to add alts for those 5k images.
