Post your screenshots!
Photoshop all the way!
I believe The Gimp can do it too, and thats free 
I was a huge fan of THE cooperative mod for Half Life 1 engine, Sven Co-Op. Here are some of my favourite screenies.

Something I made with Entmod, similar to Garry's Mod but with Sven-Coop on Half Life 1 engine

$600 to convert a picture is a bit exagerated, I think.
Yay, Paint.NET is free too, but aat least, you can use it without reading a bunch of tutorials.
No, seriously, it's not that hard. Here's your sooper-complex tutorial.
1. Open the image. Do a right click and an Open With, or just fire up the GIMP and File -> Open.
2. File -> Save As.
3. Type in the filename you want. It will automatically detect the format by what you type in. Typing "Foo.gif" will give you a .gif, "Foor.jpg" will give you a jpg.
Yes, I'm a fan of the GIMP, but it also mystifies me how people got this idea that it has a huge learning curve for simple operations. I mean, it has dedicated crop and rotate tools.
And by the way, the "ScreenshotJPEG" command in console will, well, take a JPEG screenshot. Just bind it to something with a "bind F5 screenshotjpeg" and you're done.
I've always used Irfanview. Similar to gimp and just as free. Also replaces Windows' Picture and Fax viewer (Which is a peice of crap) and with plugins, can play movies (Divx xvid/etc) and all that fun jazz.
Thats the one, I used to have it before I reformatted ages ago, but couldnt remember name.
Check out my Portal 2 map, Entrapment!

Hum, well.
You know these 6 rooms are really easy right ?
Because if not, I don't recommend you to try the challenges.

these are not just the advanced chambers (i beat those the same day i got portal) these are Advanced chambers with challenges built on (like least portals, steps, and time) and that my friend is not so easy
Ooook, I though it was the basic 6 remakes.
You should have selected one map, to see the little guy standing on the podium.
