Help with structure for optimizing Photography Website SEO

[ricfranco]

Hey guys , I am building a photography website and currently I have it setup the following way for my image galleries : https://ricfrancophotography.com/portfolio/norway-landscape-photography/#!gallery6618-6577 This provides me with an individual link for each of the images in my photography gallery but as a gallery these have obviously no content and I figured the best way would be to add the images I want to work my SEO for to individual blog posts . So here is what I did so far : - Added a link to the caption of each image inside the lightbox that is linking to the individual blog post - In order to not break the navigation I made the post with the content for each image open in a modal popup (it changes the link in the top bar but once closed it goes back to the gallery) . - I made the image inside the post link back to the fullsize image in the lightbox gallery when clicked instead of linking to the .jpg in wp-content/uploads. Now, I have some questions regarding whether this is a good practice in terms of SEO and if the fact of having duplicate images or this structure is going to hurt my SEO any way . Although both images are in different urls they ultimately link to each other this way :

Blog Image --> Gallery Image url --> wp-content/uploads/file.jpg Is there a better approach for this ? Thanks
