Image sizes explained
When you submit images along with your writing, we ask you to make them at least 1500 px wide (and 500 px for square author profile photos). Here's how to check image size using your computer.
If on a PC, follow these instructions.
If on a Mac:
1. Choose the image on the desktop and right click. Select 'Get Info'.
2. Look for the dimensions. The first one should be > 1500 (or 500 x 500 for author pic)
