I stumbled upon a few good HQ and transparent title treatments of upcoming Marvel superhero movies, so I thought I'll upload them. So far so good, however after clicking 'submit' instead of the usual 'no permissions' screen, I got a different message: "Your graphic is too small! Please upload a larger one." They are between 1600 and 7500 px wide but being title treatments they obviously don't reach 1400 px height. How to I upload them? Thanks.
