ktx2 images seem to be to big in size. #10

As you can see a JPEG version of the images is about 80kb but a diffuse.ktx2 image is about 50MB. This seems to me very large. Where comes the data from and have the images to be so big in size?

If I multiply the original data size with srqrt(2), the mipmap multiplier, the size will not be so big.

What about compression?

There are still traffic limits in persons Internet connections, thus these images are no good examples, think so.

Seems there is a low resolution branch.
