Why does the website change the size of my photographs?

Our website is tooled for both high quality and high performance in a large scale environment. Generally speaking, it is one thing to display one hundred photos on a personal web site, and a completely more complex environment when displaying tens of thousands photographs to thousands of visitors every day – and there is a real need for a finely tuned system.

To be more specific, file size is mainly a product of color density and dimension. 90% of all browsers only display a limited color range (equivalent to an sRGB color space) – when an image is uploaded it is processed to match this color range and standardizes the relative Height and Width dimensions to display files that match the exact output very closely.
