About image sizes
 

Hello I'm trying to post the images on a forum and I only have the options:

Mini / Small / Medium / Large (750px) ; I've seen other users being able to post the images in 1024px Wide.

How am I able to do that?

Thanks for your time

People who do that simply stealing our bandwidth, because we allow up to 750px embeds, not more then this, and people who sneak out bigger images just abuse the site, and will find themselves banned eventually.
