How can I make Cloudinary's URLs SEO friendly?

UPDATE: We now support a new SEO friendly URLs feature for Cloudinary images. For more information: http://cloudinary.com/blog/how_to_dynamically_create_seo_friendly_urls_for_your_site_s_images

When uploading an asset, its public ID may be changed from the original file name to a random string of characters, for example:

http://res.cloudinary.com/demo/image/upload/8jsb1xofxdqamu2rzwt9q.jpg 

You can double check your settings to use the original file name instead.

If you supply a transformation, the above URL may look like this:

http://res.cloudinary.com/demo/image/upload/w_150,h_150,c_crop,g_south/8jsb1xofxdqamu2rzwt9q.jpg

On upload, you can tell Cloudinary to use a specific file name (public id) instead of a random one, this will turn the URL to something like this:

http://res.cloudinary.com/demo/image/upload/w_150,h_150,c_crop,g_south/seo-friendly-name.jpg

You can then utilize a named transformation using Cloudinary's interactive transformation creation console, changing the URL to something like this:

http://res.cloudinary.com/demo/image/upload/t_thumb/seo-friendly-name.jpg

Cloudinary also supports applying your own CNAME (available for those on the "Advanced" plan and up). The URL then becomes something like this:

http://img.mycname.com/image/upload/t_thumb/seo-friendly-name.jpg

Or if no transformation is needed:

http://img.mycname.com/image/upload/seo-friendly-name.jpg

Cloudinary also supports supplying a folder structure to the file name when necessary, which could make your URL look something like this:

http://img.mycname.com/image/upload/books/fiction/seo-friendly-name.jpg

Above are several options available for making your Cloudinary asset URLs more SEO friendly, feel free to choose the ones that fit your needs!
