[why-not]

Someone asked about the image validation so I will explain it!

Validation on images is done using (2) passes, The first pass validates the image size allowed for the user group the member is assigned to!

If the size is below the maximum allowed, the second question is pushed to the remote server to get the other information (height, width)!

I use (2) passes, because we don't want to download a image that violates the maximum size rule, this is to make the process as system friendly as possible! This is all done using one single process, and a special (request header) that all servers understand, so we only use one remote call per image validation, talking to the remote server in a special way. I also only use one remote call if there are (1) or more images in a signature and those images are all on the same remote server!

I have put a lot of time in load tesing and trying my best to make this very system friendly! Sure I know of easier ways to deal with image validation, but they are very resource intense. Which is what I do not want and you will not want, this is one of those times that one would need to reinvent the wheel, and that is what I did!
