File size using JavaScript possible?
Hi all, please excuse my ignorance. I'm one of those people who knows nothing about JavaScript beyond how to copy/paste other people's code.

On my website I have a large number of PDF's available for people to download, and I'd like for my users to know the size of the file before they start downloading. Previously I've been using SSI's to do this with reasonable success, but for some reason my javascript (and even some of my CSS) kicks the bucket when I've got SSI's on a page.
So my question is, can an 'fsize'-like result be achieved using Javascript? Alternatively, does anyone have any ideas why my SSI's are affecting the rest of my page like this?
Thanks in advance.
