Using reproject for large projects

Hi all. I wonder if anyone could give any advice on the best wasy to use reproject for large projects. It seems to me that reproject basically crashes (gets killed) because it’s just too memory intensive. It seems unusable for science cases that have more than 10 or so images.

We have 480 exposure on an object and it seems impossible to use reproject.

Can you describe this a bit more? How big are your images? Can’t you just reproject them one-by-one in a loop so tat you have one main image and then reproject image 1 to that main image, and the image 2 to that main image (so tat image 1 does not have to be in memory at the same time)?
