Here's my take. I've committed myself to entering every week if it's at all possible (i.e. as long as I'm not on holiday or ill or otherwise physically can't get to the computer).
P.S: I figured out how to edit the image size! 
On the very last stage before it puts the image into your post (the box that comes up first) you go to where it says “image size” and change it! You just have to be careful to keep it proportionate 
Sorry to anyone who's already figured it out and thinks I'm a bit slow 😛
