go to photobucket and create an account, use either the bulk uploader or just the regular uploader. then you can tag your pictures and file them into seperate folders or w.e you want to do. just remember to upload them here use the IMG code. when you make your account and upload your first pic you'll see the IMG code option as well as many others.
Alternatively, you can upload photos to the TF servers. If making a reply, click on the "go advanced" button. If you scroll down you'll see the "attach files" options area. Click on the box and you can upload files from your computer that'll then be attached to your post.
