I haven't updated my look in a while, so I've decided to do some tweaking. In the process I discovered that Yahoo! Photo doesn't allow outside links to images. (Recall this post.) PhotoBucket does however.
PS: I suddenly discovered that my template was distorted in Firefox. Tip: if you have a div that is holding two other divs (as I do: content holds main and my sidebar) then you have to add display:table; in the stylesheet reference for the content div. Apparently, I am not the only person to have had this problem. I found the solution here.
