If this is about tagging images with people keywords (names) that can be seen on web sites, the way to think about the project is to build it around industry standards such as IPTC, the standard used by news organizations around the world for adding keywords, captions, etc. As long as you choose photo editing software that can export IPTC keywords and a website builder that can display IPTC keywords next to an image, you can do all the work in the photo editing software, export the images making sure to embed the keywords, and those embedded keywords can be read in by any compatible website. What I wrote in this paragraph is not specific to Lightroom Classic, you’ll want to keep it in mind regardless of which photo software and website service you choose.
Fortunately, Lightroom Classic can fit right in with this. You could approach your project like this:
- Use the tools in the Library module to add people keywords to images as needed. Lightroom Classic has features for adding keywords in different ways depending on how you like to work, such as drag-and-drop, click-to-apply, autofill, apply one keyword to many images… Lightroom Classic also has face recognition for automatic tagging; although it isn’t the most advanced, it works OK.
- When you use the File > Export command to export images in a website-compatible format such as JPEG, be sure to set the options so that keywords are included.
- Once you have a folder full of exported images containing keywords, if you upload those to any website that recognizes IPTC keywords, an image can appear on a web page with its keywords next to it. Some website services that support keywords are Flickr, Smugmug, and Zenfolio.
Also, the major OSs for desktop and mobile devices automatically recognize IPTC keywords in images. For example, if you send a family member a folder of images with people keywords and all they do is copy it to their iPhone, Mac, or Windows PC, if they do a search using the built-in desktop search (not even opening any apps), those keywords will be found and will list those images in search results.
Note: Lightroom Classic does have a Web module that can generate web pages (not full websites) if you already have a web hosting service, but I haven’t looked at whether it preserves keywords. It might. I wrote my answer above assuming you are thinking of uploading the family images to private pages on a website you created using one of the well-known website services.
