This code will allow you to insert an image from a file posted online. This is basically what the "Insert/Edit Image" button on Blogiversity does for us. The code for inserting an image is: <img src="imagename.gif"
width="x" height="x">
You must first upload an image online (this can be done through your blog files). Then replace "imagename.gif" with the URL of your image. Then just replace the "x"es with the dimensions of your image. You can do this on firefox by right clicking an image and clicking on "Properties". This will bring up some stats, including the width and height. Drop the numbers in and paste the code.
For example,
<img src="http://www.blogiversity.org/sitefiles/1000/blogiversitylogo.gif"
width="543" height="80"> should look something like this:
Every man dies, but few truly live. Live your life to its fullest, every day as if it were your last.
