Photographs

Hello everyone,
I have built an art gallery world, Malalclypse Gallery, and published it on the community lanbs.

I’m trying to keep it quest compatible, but I think the photographs of the artwork are taking up a lot of space.

Does anyone know any clever ways/formats to use to keep the size and detail, but take up less space??

I’m a bit of a noob so sorry if I ask a lot of basic questions.

You could crunch compress the textures

thanks for the suggestion. would that lose some of the quality of the image?
