The following is the main method of inserting a picture inline in your post.
If you'd like to use an online server other than 8thcivic to host your images, you can use one of many free services like tinypic.com, imageshack.us, photobucket.com, and many more. Just upload your files and gather the URL code to the image you've uploaded. You'll have to insert the code that looks like
[ img] www. tinypic.com/mypic.gif [/img]. Just without any spaces in the line of code.
The "[img]" starting and "[/img]" closing tags will make your picture load into the site.
