I use http://www.photobucket.com
. You can upload your pics, organize them into albums, and underneath each picture, is a link you can copy so you can paste photos here in the forum, or in E-mails or on a website, or just give somebody a link to the picture. It's simple to use. For the forum, you just copy the [IMG] link. It's the bottom one under the photo.
As for that bus, if you want to use it for parts, it might not be a bad idea for $600. But I really wouldn't mess with that motor if it's overheating and doesn't have good compression.
