Topic: loadMovie, ok to not exist?

I've got a movie that loads a background image, loadMovie(), depending on what a variable is set to. This var is set on a php page and loaded into flash via loadVariables(). I've also got another image that I may or may not be loading in the same manner... my question is... is it ok to NOT specify the path and keep the loadMovie actionscript in tact?

Example:

loadMovie("images/" + homeImg + ".swf", imageDrop);

Where homeImg is not declared in the php file.

Or should I load a blank movie?

in case the file is not found it will most probably create a blank movieclip.

Cool, so that's not going to cause problems then I assume. Thanks grum.
