I have a sub page on a website that features an image gallery
/gallery/gallery-name/ - this page contains a common description about the content of the gallery and thumbnails for the gallery items. The thumbnails are linking to a subpage
/gallery/gallery-name/image-x/ - these subpages contain the image in higher quality and the thumbnails of the other images.
My question is that should I use a canonical on
/gallery/gallery-name/image-x/ that points back to
I have already read about canonicals, I am a little bit familiar with them. Therefore I know this case is not about an exact duplicate version of a page. However I am not sure that it is a good idea to have hundreds of these image pages (on unique url's) since they don't have too much unique content. Only the high quality image and the page title differs (every image has a number).
Other thing is the "parent-children" relationship between the two pages from the content's view.
So is it possible that the high quality image on the image sub pages is enough unique content? Or is there any chance that it will be considered as content spam because the difference between the image pages is only one
.jpg file and one word in the title?
I am a bit afraid to release these gallery pages, so I am thinking about to play safe and use a canonical on them. But I would really appreciate if somebody with more experience could help me to make the best decision.
