What does a high pass filter do to an image?
A high pass filter tends to retain the high frequency information within an image while reducing the low frequency information. The kernel of the high pass filter is designed to increase the brightness of the center pixel relative to neighboring pixels.

Why Gaussian filter is better than median filter?
