What is the best way to create a image gallery website?

I'm looking to create an image gallery, to show images I have taken. Is there any software that would be great for this? I am open to any suggestions.

Would prefer if this was:

• Lightweight
• Able to easily add images
• Maintained

I am looking for something similar to this: kaiser.gallery

I have tried out creating this through Ghost, Grav and have previous experience with WordPress (Too bulky, with many unneeded features).
