In your options before it does the exporting, you can change the image 
type to JPG and also change the size of the image.  I do not remember 
about setting the "quality" of the JPG image there, though I know that I 
have software that can save JPG images as a "lossless" type.  If the 
size of the image is too small, you can resize it in many packages, but 
the issue with the "original person" was he had 200 images/slides to 
make into JPG images.

If he would let us know what the images are for, there may be an easier 
way to convert the presentation for that specific purpose.  I have 
converted one to HTML before for an online version of the presentation.  
I have used images and run an HTML "photo" album software [free] to make 
it work as a slide show with transitions for online use.  That software 
took smaller size images and resized them to be all the same image size 
I chose for the slide presentation.  It all depends on the use.
