Hi @murelot
Thanks for getting in touch with us.
I’ve just had a look at the images you shared with us. The FooGallery settings used seem to be ok. However, your fouth image, which was a screenshot of your page in the WordPress Block Editor, may hold the answer to why the images appear like that.
From that image, the gallery doesn’t appear to be one created FooGallery. It looks like you did create that gallery by adding those images to that page using the WordPress Block Editor, or some other page editor/builder.
Kindly note that once you’ve created a gallery using FooGallery as you’ve already done, all you need to do next is to copy and paste the shortcode that is always automatically generated for each gallery into any page or post to display your gallery. If you’re using the block editor, you can paste the shortcode into the HTML block.
You can have a look at our Getting Stared guide (https://fooplugins.com/documentation/foogallery/getting-started-foogallery/foogallery-101/) or this short YouTube video tutorial (https://fooplugins.com/documentation/foogallery/getting-started-foogallery/creating-galleries-video/) we created on how to add a FooGallery to your page.
Please let us know how it goes.
Regards,
Elvis.
