Well, I think it downloads it to cache it, but it doesn't look like there's any security or any limiting of cache size, so I guess there's no difference bewteen that and downloading them all to your server. And if you use the code in the post that eliminated the cache, thne I guess you're pretty much back to what you have.

I don't know that curl is any better. I guess it's a little easier to set headers and manage any errors that might happen, but if what you have is working for you, then it doesn't matter.
