The resizing itself might not take so long, but the downloading of the images. Typically the downloading of a 400x400 image will take longer than its resizing on even a moderate speed processor.

You basically have two ways to solve that:

(a) Store your images in multiple resolutions on your server (or your hosting service) and download the copy that is already fitting in size.

(b) Do the resizing on your server (or your hosting service) on the fly. So only relatively small images get transmitted.

In either case, be aware that photographs loose a little bit of sharpness when simply resizing them. So you might want to do some sharpening afterwards too.

It is not a question of how many images you have. You can downscale them by a simple script and have the sharpening done in that script also. The downscaled images take only a small fraction of the size of the originals, so it's not a matter of space either. It you put the downscaled images in a separate sub-directory you can even keep the original file names. Just apply the sub-directory name in your HTML code. That approach worked fine on my website and I have thousands of images as well.
