the zoom level 13 weights 1.2Go. Do you think love2d can load such a big image ? My laptop has 16Go of RAM.

It will be nice to load only needed images, cut big image to something like 4096x4096 pixel chunks, load what you see and near neighbor chunks only.

If your image is .PNG, you can compress it with something like PINGO.
