With AS3 you can load the image as binary data (Base64 encoded).

Base64 is superfluous here, since you can load raw binary data - see

You can't send raw binary data over http, it has to be Base64 encoded.
This part is required in the Coldfusion page:

We are making a game in which people have to quess what's on
a photo while viewing it through a little moveable hole. The
images will be loaded from the server. The problem is
caching. To cheat is easy...
watch the cached

As I mentioned earlier in the thread, and Muzak just mentioned also,
calling that technique
A solution is to convert the image into a textfile which is then used to
draw the image on the screen using bitmap drawing tools.
This, of course, is easily hacked by anybody with a copy of Flash
because they can read your textfile and draw the bitmap themselves.
The next step is to encrypt
to ByteArray.

watch the cached files. Is there a way to prevent flash from caching the
loaded assets or
I think the caching is controlled by the browser, not Flash itself, so
I don't believe there's a way within flash to prevent caching.
Maybe you could do some trickery with the images that makes it harder
for the person looking at the cached stuff to see it. Like, split up
the main image into
If you're using AS3, then load the image via flash.net.Socket (a
direct socket connection to the server) rather than via the normal
image loading mechanism - then use loadBytes() on the Loader class?
I think that gets around it.

at the SWF from the browser's cache, they'll just see a big black
rectangle but within your app, the photo is visible.
Just a thought.

Of course, that doesn't really prevent caching as much as it prevents
the broswer from handing Flash a cached copy the next time
Can't you just put this in your page header:
meta http-equiv=cache-control content=no-cache
to prevent caching?
