Well how can I get images to appear on here then? That is without them being somewhere else on The Net?
You really don't need to show us pictures of this particular "problem" because its not one.
Now, if you just want to know for future reference it works like this.
You're machine is probably not permanently hooked to the internet. Even if it is, its not handeling requests for people to download images off it. Trust me, you don't want to setup your machine to do this unless your really serious, experienced, and technically knowledgeable to do it.
Your best bet is to post it to some FTP space. FTP stands for File Transfer Protocol. All of these websites you visit, people use FTP to put their sites on FTP servers that are configured for people to view them from the Internet.
Nearly every major and minor Internet Service Provider gives you some sort of FTP space to play around with. I get 5 MB per e-mail, some people get 5MB total, some get 10MB, some get 2MB...it all depends. Regardless, what you should do is ask your ISP (service provider in other words) on how you can access your FTP space and what software they recommend you use to do it.
