We all know about the advantage of using png as images on web pages (saw the blog on Wikia, but forgot to save the link, sorry).
 * using translator

The need for preliminary compression
But there's something about what you forget. The program that creates these images are often not adequately compress the resulting image. (if they even include such algorithm) http://ru.mlp.wikia.com/wiki/Файл:My_Little_Pony_Game_Elements_of_Harmony_RUS.png
 * screen from android for example: = natural bmp
 * Don't let the extension to deceive yourself. Always look at the size and weight of the file.

How to compress images before uploading it to the wiki?

 * 1) Popular program for working with images / special add-ons or programs with compression algorithms.
 * 2) Online services:
 * 3) *http://tinypng.com/ (for images, has its own plug-in for photoshop. excellent compression, but a noticeable color distortion and squares)
 * 4) *http://www.smushit.com/ysmush.it/ (for gif)
 * 5) *etc.
 * 6) To embed a ready-made algorithms (or develop new) compression in server.

Build-in compression. How does it work?
At the moment it does not work. As you see before ─ all the received images based on the original, not the compressed version. Server also stores the duplicate files (as if that makes sense). For example, in situations where the wiki two different language sections on the same topic does not have a shared media storage. However, that is another problem. Apparently the new image server also does not have such system. (try compress) http://vignette2.wikia.nocookie.net/wikies/images/e/e3/Tomb_Raider_Wiki.png/revision/latest?cb=20131228195511&path-prefix=ru
 * here would be very useful block diagram, but sorry, I don't know how to draw them.
 * 1) Server get image.
 * 2) Check for duplicates
 * 3) Create own/united(combained) version of file
 * 4) Optionally, creates a compressed version of the file and founds all thumbnails on it.
 * the desired algorithm with a good balance between size and quality. at least getting rid of it uncompressed images.

Why so important
"What is the problem? Well stored on servers, terabytes of useless information, that's okay." Not quite. Because they are stored not just in the archive. It each time come to users devices. A huge flow of information. Kilowatts energy wasted on the transmission of noise.
 * although the gain in the size of the thumbnails is not so huge: 10%-30%/up to 50%, it is still tangible value given. what images make up a large part of the traffic in the transmission page.

All information presented here is an introduction needed to make next step.
