There are a few ways to post pictures. One of the most common ways for this site is to use www.photobucket.com
. Just upload you pictures to photobucket and then when you are viewing you album on photobucket there will be a specific URL link for sites like this. Just copy the link and paste it in your post and the picture will appear when you submit your post.
Another way is to use the image command. Just type [IMG] and then upload a picture from your computer straight to TCS by clicking on Manage Attachments. Then after you are done that just type [/IMG] to complete the command.
Those are probably the easiest and most widely used ways. Good luck! I can't wait to see some pictures.
