The Guild already supports high res image embedding. What prevents using the same concept for profile pictures, and then have the server scale it down, and perform all the necessary alternations (such as the displayed resolution, as you mentioned)? For instance, is there anything that would make it impossible for the server to take these image URls, make the alterations server-wise, as if it were a local file, and display the altered output?

I'm fairly sure the guild doesn't actually store any images, it just points to where an image file is stored (I believe this is how websites work – I don't work on web much (read: the guild is the first real web coding I've done), so I'm not certain on that.) so it can't do anything to the image.

I'm aware that it doesn't store them, but it is completely possible to edit them. You just run the image through a "filter" of sorts before output, and it displays it according to the commands. For example, Mahz has a hack that alters profile pics images larger than 150 X 150 to attempt to display them correctly. You're correct that it doesn't do anything to the image itself, but it can change the display.

PHP has a couple modules for this, GraphicsMagick and ImageMagick. I think Node.js has a library that will interface with the PHP modules to do this. So long as the two (PHP and Node.js modules) are installed, then it's probably just a matter of taking the time, reading the documentation, and doing it. Someone with the javascript skills and wherewithal could probably write a patch and submit a pull request if they really wanted it done quickly.

Once I've finished my computer repairs, I may go ahead and have a crack at it myself.
