Whew! I just went through all my blog history, updating all the broken images I could find.
It really goes to show the importance of not linking to images posted on the Internet, and instead saving them and then uploading them to my personal web space on the LP server. At a certain point I started doing that, and all the images after that point were visible (not broken).
It was also kind of fun to go through all those old entries to see what I was thinking at the time. It was also amazing to see how many useful posts I had compiled, especially the computer programming tips and snippets.
