 Null Images

I've noticed a lot of null images recently, often followed by the player mentioning something in the game thread about pics not showing after a successful upload. Any idea why an upload would return an image key, but subsequent access returns a null image? I guess I've always figured it was an issue with the player's connection, but it seems to be happening more often and people seem confident they've sent pics correctly.

Possibly a problem with the june changes correcting some picture upload. I'll need to get some more information (what fails, when..)

I've never seen it happen to me (that I know of), but the symptoms are:

- player sends a normal jpeg via sendImage
- sendImage returns a valid key after upload
- receiveImage with the correct key returns a null string

This has happened in Courtroom (especially), Spin the Bottle, Strip or Die, Human Paperboard (and likely others). Note that the image key is almost NEVER retrieved immediately, so there's likely some time that passes between when a player sends and when another player receives.

This wouldn't be a security feature, would it? For example, accepting the image and immediately deleting if from a "bad" IP address...

Possibly a security feature, but not likely. I guess an error in some algorithms server side.

If possible I'd like to know an example of image key that fails, from anybody.

Next time I see it, I'll grab the key and report it.
