Image Duplicates - Does Google Penalize on this?

[NakulGoyal]

Do you have an Image Sitemap created and submitted in your webmaster console ? If not, I would suggest you do that. Other then that, if I were you, I wouldn't worry too much about this being an issue at the moment. Google is smart enough to understand this as a CDN situation. As I said above, doing an Images XML sitemap should be all you need to do in this regard. I hope this helps.

Nakul, would you recommend this practice to all sites with a decent number of images?  Or is it only important in this case?

Dear Nakul,

About the image sitemap, what do you recommend :

1. use the attribute on the current sitemap withing the prop or build a separate sitemap for images.

To be honest Im not sure what is the best way and Im worry about sitemap related issues

Waiting your response

Thanks for the response Nakul. So, in the image sitemap, would you recommend to add all the locations of the images or should I just mention only one. If one, which should be that and any reasons for choosing the same. If this does not cause a duplicate issue, it is fine with me.

For better indexation I can certainly have a sitemap but would like to know on how to go about this?

Cheers,

Jesse, yes, I would recommend doing this for any site with a considerable number of images. If you want your images to be found, it won't hurt to do an image sitemap. Definitely recommended. Google webmaster console then gives you a good read on how many of the images you submitted are already indexed as well as a count of the pages those images are on, that are indexed.

[NakulGoyal]

Akhil, at any given point, there's only 1 of those 3 URLs of the images that would appear on the site. I would therefore only choose 1, the one that is primary / most important to you.

Claudio, I would recommend doing a separate images only sitemap in the right format. See these links for more details:

Looks like there is enough interest here for a full blog entry on image sitemaps.  Nakul?  Anyone?

Cheers Nagul!

Give it a go.  And let me know when you get ready to publish it and I'll share it around.  It would really be quite a useful topic to learn about.
