You can use the default Windows XP program, Paint. You can also download demo versions of Paintshop Pro or Photoshop (

For Paint, go into
start --> all programs --> accessories --> Paint
Then use the "open" command and direct it to C:\Program Files\Guild Wars>Screens (change the drive letter if it's not on C:\) and click the picture you want it to open. Then you can use the editing tools to reduce size, crop, etc. Be sure that when you save it, you save it as either a JPEG or GIF file...BMP files are HUGE and most free picture hosting sites don't accept them.
For hosting and linking your pictures:
http://www.imageshack.com
http://www.imagecave.com
Try those.
To post a picture, type the following without spaces:
[ img ] the URL of the image's online site [ /img ]
That should do it.
