Question about if conditions - load/unload movie

Hi,
First I want to say how much I appreciate kirupa.com. I am still an amateur but I have learned so much from this site. Thanks!

I have created a simple little slideshow that dynamically loads external images. I didn’t do it with xml because, frankly, I’m not that good yet.
I am simply loading the images into an empty movie clip with loadMovie.

What I need to know is if it is possible to tell Flash to go to the starting frame of the movie if it doesn’t find the image it is trying to load? The images live in the folder with the flash file on the server.

I would like to use the ‘if’ condition to tell flash to go to the first frame of the movie if it doesn’t find an image…is this possible or am I totally out in left field?

Thanks
:}
