I added the archon you posted awhile ago, with the text that i changed
I also added the d3 one you made too
I couldnt resize that without stretching it, so i resized it to be the height of the other logos (250px) but left the width to preserve the aspect ratio, which made the final image 518x250
The width was too small (nearly 100px smaller then what it should be) so it looked off center on the page (because its meant to center things that are 600x250)
I tried to change the way the css centers images so that it could center images of different sizes, but i couldnt get it to work
Instead i added a transparent layer to the image, to make the image 600x250 which makes it center like the others
Make sure all logos you make are 600x250 (or a multiple of that) if you make more
I also changed the way logo is centered, so tell me if it doesnt work
I know the site doesnt look right on most (probably all) mobile devices, unless you use the mobile version of the site (which is crappy), i may fix that at some point (thats the chats fault though, not the logo)
Basically it breaks at low resolutions, but i figure everyone uses a laptop/desktop with at least 1280x720 resolution when they come here so im probably not going to bother to fix it
EDIT:
2 more logos were deleted from tinypic, they were all uploaded at different times so i dont know why so many are going down at the same time, ive restored the missing ones
