Empty MC is cutting off view of dynamic jpg's

I have a main .swf that loads other .swf’s for each website category (portfolio, contact, downloads, etc.). For the portfolio page I am dynamically loading jpg’s for an image gallery. However, the empty movie clip that the pictures are loaded into is cutting off the pictures about 5 pixels on the right and bottom. The movie clip width and height are both 0. Should I declare a size for the movie clip in code somehow? Thank you in advance for the help.
