What size page should I upload?
For the sake of the online viewer, it is best for files to have a height which is a multiple of 400 pixels: 1200, 1600, and so on. That said, any image of relatively high quality will be accepted. You should also note that:
- The image should be cropped to the size of the page.
- Panels and bounding boxes should be parallel with the edges of the image.
