This seems like the most basic of all features: images open bigger when you click on them, either when single images or when in galleries.
How is it possible that this doesn’t work in Ghost (or requires hours of searching for help)?
I insert an image or gallery and, when clicked on, either opens bigger. This is epsecially important for galleries since the images are small.
What am I missing?
Because it is up to the theme creator to include lightbox, it isnt needed for most sites and is more a one off use case. So look into the theme you use, search in here as maybe someone has explained how you could add it, etc.
Images open up for me using the Source theme. What theme are you using? The Gallery card might be just what you’re looking for. If not, could you provide a link to your web page?
