At the end of many image URLs, it has ..whatever.jpg?m=NNNNNNNN where NNNNNNNN is some number. What does the number represent? Usually I just remove it when I display the image in a forum or something. Is it a user or image ID of some kind?

This is using Gallery 3 RC2.

Thanks,

It is for preventing caching issues.
Not sure if the http://codex.gallery2.org/Gallery3:Modules:embedlinks module helps in what you are after or not.

Thanks for pointing me towards that. Helps getting the links anyway. Guess my main question is, should we be including that number in the URL for caching/performance reasons?

Thanks,

You can use uls without the number.

You can safely ignore that value. By using that value, we can have your browser only download an image when its changed. Otherwise we have the problem that you rotate an image and we show you the old one, or alternatively we have to have you download the images every time you view a page (really inefficient).
