My advice is, to setup a free flicker account, or somewhere on a website that is for the same purpose (smugmug, google's file sharing, even Bing has one) that you can upload your pictures to. Then you come here and post the BBcode link, that the site will give you to post here to see the pictures. Each site is slightly different, you will have to do some reading.
if you try to upload directly to here, you have to crop and resize everything to fit file size limits and stuff, which is equally if not more difficult IMHO.
Here is my example:
