The question isn't the number of pics, but how many times your server
gets pounded on...
Or are you planning on scaling down hundreds of pics on *ONE* page on
the fly? For sure, don't do that. Or, you can do it, but cache the
results of the thumbnails you displayed, so you only have to really
scale them in PHP the first time.
The real question is:
Why do you need / want the original large picture?
What use do you have for it?
Storage space for hundreds of digital camera images is pretty
predictable -- You could figure out exactly how much drive space you
need.
