Delivering League of Legends

PS: I can make the logo bigger if you want.

Delivering Diablo3

Delivering FRAPS

If you want I can make the background from some game of your choice!

Same here, I have the retail version, DRM-free

For games that you can already buy on Steam, you can use the default header.

For example, Bad Company 2 is http://cdn.steampowered.com/v/gfx/apps/24960/header.jpg clicky.

For other games, just use:

• http://cdn.steampowered.com/v/gfx/apps/__24960__/header.jpg
  and replace the bold part with the game ID, which you can learn by going to the game's store page (for example
• http://store.steampowered.com/app/__24960__/
  for BC2).

How do you really put Tribes on Steam? It allways launchs an error for me.

Delivering Mass Effect 3

Here's another alternative - by me.

Delivering Alone in the Dark and Zelda Wind Waker - both by me.

Delivering Postal 2

You need to download the beta update for Steam. Instructions here.

Are you in the latest beta? Go to Steam settings and opt in, you should see a "Set Custom Image" on the right click menu afterwards.

if i can change gallery.........i want fifa 12(image) if possible thanks :)

I dont know XD

Because I really couldn't be arsed going to the desktop? Besides, I like using Steam to launch my game related stuff... Means my desktop remains (gaming) clutter free.

EDIT: further down, someone has asked for Skype... I'd say thats less useful / nessecary on steam than fraps

Delivering Counter Strike: Source Beta

Firefall and also Krater for the betas of those games

Splinter Cell Chaos Theory 1, 2

Majesty NOT-HD to fix the steam library error that shows the HD version blank and the SD as HD. Then use the regular HD one from the steam store on the HD link that is blank.

...and yes, I wanted it to look hokey and like a slapped on fix, because it is still broken in the library itself. :)

One for King Arthur Collection and also Hector: Badge of Carnage that I had requests for yesterday

Here are some Kingdoms of Amalur: Reckoning alternatives: dark logo, woods fight, trolls

Here are a couple for Aion 1, 2 and also three for Tera 1, 2, 3

Some of those games are on Steam. Use this link

http://cdn.steampowered.com/v/gfx/apps/xxxxxx/header.jpg

and replace "xxxxxx" with the games Steam ID and you'll get the picture.

Also, here's a bunch. I see Alice all the way at the bottom left. and Crysis 2 near the middle/right

I will try after I update the main post.

There is really not much media to work with for Cardinal quest, here what I could do quick with what I found.
Cardinal Quest

The Elder Scrolls: Arena
The Elder Scrolls 2: Daggerfall

Not really my best work due to a lack of source material to work with. Arena looks ok, but I'm really not happy with the Daggerfall one. I might redo it later on and try to make something better if you don't like this one.

Hello Kitty Online was an easy one. :P
