Recently many of my friends on social networks start complaining that they are started seeing low quality of images which they used to see in clear. Well this is because most of them are using mobile internet for browsing the pages. In Bangladesh the largest telecommunication provider GrameenPhone wasn't using data optimization policy on their network.But as their mobile internet customers grows rapidly these days they needed to use data optimization (pre-cache) for better network flow. Read more about GP's data optimization here http://www.grameenphone.com/node/655. This reduces the image in quality resulting extra free bandwidth. So the customers going to experience slightly better speed :D But some of us don't like to see nasty low quality images actually :@ so what we do is pressing ctrl+shift+r or ctrl+F5 to reload the page in high quality again.

 The above picture on facebook displayed in low quality on my PC. As i am a firefox user so i found a way to prevent loading low quality images for ever :D

(cheers). What we need is to modify the HTTP headers requests. The methods mention below is easiest for normal user. I have used Modify Headers add-on for firefox for this purpose.
