Sig Filesize Rule

[Riddell]

I got my sig removed because it was 10kb over the size limit.

Now, I understand the height and width rules but what is the reason for the filesize limit considering the image is hosted on my Dropbox account?

Not complaining, just curious.

The bigger the file, the longer it takes the page to load.

...well, that seems logical to me, at least

It's 2012. <100KB images will load almost instantaneously. The OcUK logo alone is greater than 20KB...
