How to Upload Images
There are 2 different places to upload images:
- Header image in Details Tab which will only accept picture in size of 1440x810 px.
- Content tab
- you may upload images in the size of 640x640 (minimum size) or other bigger square size image i.e. 700x700 or 2048x2048 will be accepted as well, as long as they are square.
- Size requirement are stated at the image upload area.
If you have the correct image size but still have the error, perhaps you might want to try doing it using Google Chrome or Edge. People are reporting having issues on Internet Explorer, Safari and Firefox.
