Before uploading your content you should prepare your files as follows:
- Drag the images folder into the Schoolzine Image resizer to reduce the file size for all of the images. This will reduce the time it takes to upload your files.
 - Ensure each folder is no larger than 150mb.
 - Zip your images folder.
 - Zip your attachments folder.
