(er, I should have said +[NSData... not - )

I'm working on an app that downloads various images from Flickr.
Sometimes, I'll get back alist of hundreds of photos, and will
build URLs and in a separate thread, try to download thumbnail
images for all of them - using -[NSData dataWithContentsOfURL].
Once I get back the data, I save it out to disk and then use it
later for displaying those images.
Sometimes - and I haven't been able to pin it down 100% - all that
will eventually display is a pure white blank image. When this
happens, it happens for many images at once. It seems to happen
most often when my home network is congested or I am trying to load
so many of these images that they take a long time.
Is there a timeout on -dataWithContentsOfURL? What gets returned at
that point?
Regardless of what data gets returned, I write it out and move on.
When I go back and read one of these "blank" images using -
dataWithContentsOfFile, I get a valid object, but the data it
contains is zero bytes.
Thanks,
Blake
