Random block standalone - error issue

I know this is low on the priority list, but I thought it wouldn't hurt to ask in case someone figured the problem out and just has never posted the answer here. I've been playing with the random block as a standalone. I'd like to incorporate it into my online journal. While it works pretty well, it does throw an error message pretty regularly, that seems directly connected to the fact that it is trying to call upon the image that is used as the highlight photo for a sub-album. For some reason the code chokes on that. That is the only problem I've encountered, and I don't know enough to know how to fix it.

The error message is:

Fatal error: Call to a member function on a non-object in /home/virtual/***/fst/var/www/html/gallery/view_photo.php on line 70

This is the line being referred to in the view_photo.php:

list($imageWidth, $imageHeight) = $image->getRawDimensions();

Does anyone have this worked out?

Thanks!

Hi,

I'm using this code :

if (fs_file_exists(CACHE_FILE)) {
