I plan on making a portfolio of images for my site. I want to have a small thumbnail and a larger version of th image. When you roll over the thumbnail the large one pops up.  
I know how to do this but I want to keep my file size to a minimum. So for those technically inclined out there here are a few questions.  
Will loading Jpegs from external files be “much” slower than haveing a full sized jpeg in my library?  
If I Keep my jpegs in my movie library is it more efficient to have the thumbnails made up from the orginal image (just shrink them down) or should I load in separate jpeg thumbnails.

Thanks guys
