The way things are set at 23hq is to assign an address to each photo right? If I upload multiple photos, the addresses will be in numerical order.
Now, I linked one of my private photos in a discussion forum because I wanted to share it with the forum only and not the rest of the world. The photo is visible in the forum, even though it is set to private. That isnt my concern. My concern is posting it in a forum will also display the address for that picture. By changing the "last" digit of the address, they may be able to see my other private pictures.
I uploaded these pictures for use in the example below
Example: I link this photo onto a website or a discussion forum
Although it is private, the people in the forum can view it.
But when I uploaded this picture along with other pictures that I want to be private, 23hq assigns it in numerical order. So if someone wanted to, they could change the address to 5006966 or 5006968 and they can see those private photos which I didnt want them to see.
Maybe 23hq can use a Random Number Generator when it assigns addresses to the photos.
