Image URLs - best practice

[McTaggart]

Hi - I'm assuming image URL best practice follows same principles as non image URLs (not too many files and so on) - I notice alot of web devs putting photos in subdomains, so wonder if I'm missing something (I usually avoid subdomains like the plague)!

From an SEO standpoint, I'd say that the URLs generally follow the same principles. Unfortunately, now that Google directly caches and displays your images, image SEO isn't worth quite the effort it used to be.

In most cases, if images are on subdomains, it's for technical reasons unrelated to SEO. People might do this for load-balancing or because they run a 3rd-party CDN, etc. There are more sophisticated ways to do this so that the images all live on one subdomain with the content, but they can be more labor intensive and more costly (and some platforms just don't support them natively).

Hey Luke,

You're right. The same URL principle implies on the images URL. And, I really do not think putting images in subdomains is a very good idea. You also need to avoid the typical images names like DSC4566.jpg rather you should go with something meaningful that contains your keywords like /images/Burj-Khalifa-largest-building-world.jpg  -----  (I am in Dubai these days :p)

Hope this helps!
