This looks like a small glitch.
Using IE to view this page:
And use firefox to view this page again, you will
notice the dir title on IE locates at the bottom of the
dir thumbnail, while firefox display the title on the
right side of the image. I tried to go thru the code,
but seems like it has nothing to do with phpgraphy.css,
maybe it's in the index.php, but I don't know what part
of code to look at.
