Note: Image file metadata (from photoshop, lightroom, etc) does not auto-import into the image’s Title, Description, Tags or Photo Credit fields of the image details. This data must be manually entered via the website editor.
Adding information to your images is important for both the viewer as well your site's overall SEO. You can add page title, description, keywords and even give photo credit if you are not the one that took the original image. Here is how to do so!
1. Select Content
2. Select Image library under Libraries on the right sidebar
3. Select the Edit button under the image (the 'eye' icon)
4. Next, fill any and all information you wish for your image. (make sure to 'save' when you are done)
