@vinoman Right now, if you click on the pictures, they will take you to just the photo itself, where it is located in your media library (on your server). E.g., the first one links to: https://www.graphicmagic.net/wp-content/uploads/2012/02/gm-parts2.jpg
When you insert the picture on your page, the box where it says “insert in post” has a lot of options above that. One is the URL that the picture should point to. You can change this to whatever URL you want.
If you click on the HTML tab (as opposed to the visual editor tab), you can see how the link is set up. E.g., a basic link would be <img src=”yourimage.gif”>. You can just replace the “https://yoursite.com” with whatever URL you want. Does that make sense?
If you’re wanting them to go to a page where the artwork can be purchased, for example, you can just change those links. If you just want a pretty gallery of images, there are some nice plugins for that as well.
