What Immortal Flower likely meant was that she first puts them on her website, then uses bulletin board code to attach them here. Alot of forums will allow you to load the picture onto the host server, but I have never tried that option on this board so I don't know if this one will let you do it. This is for people who either don't have a website or who do not want the extra hits that being linked to a busy board will cause.
I am going to link to a picture on my website:
In order to see the code I have used, you can click the "quote" button on this post, and it will come up into your reply box with the code showing. The http://
etc is the URL to the page on my website that I am linking to. This can be determined by opening up the page and copying what's in your address bar. If you are wanting to link to a picture on another website, you can get the URL either by clicking on the picture to bring it up in a window by itself and copying the URL, or by positioning your cursor over the picture, right clicking, and copying the URL from the properties box that pops up.
You can also click the vB Code [help] link that is to the upper right of your reply box to get detailed help.
This will help you if you have a website or want to post a picture from another website.
I hope it helps, anyway!
If you want to load your pictures onto the TCS server, and this board allows it, I'm sure someone else can come in to help you.
