LaTeX Question

[CycloWizard]

I've been writing everyting in LaTeX for a while now and like it pretty well. Unforunately, many scientific journals keep raising their image resolution requirements to the point where I now need images that are 600 dpi. This makes a typical article pdf about 70 MB, which is obviously too large to e-mail to people. I figure if I can get it to use 100-150 dpi images, it will be e-mail-able, but I haven't been able to find a way to do this yet. Does anyone know of a way to compile it while including the images at a lower resolution? I know I could change all of the images to a lower resolution and keep two copies, but this becomes extremely tedious in certain instances, such as in my dissertation (which has >100 images).

PDF is a vector graphics format. You should check out the options on whatever it is you use to convert bitmap images into PDF (or EPS).
