What's next: You'll be taken to the editor page to upload photos, crop them, customise and preview the final print.
Do I need to crop the photos before uploading them?
Nope. During the upload process, the website will automatically crop the photos to the right aspect ratio and sizes. There is also a cropper tool you can use to make fine adjustments.
When I tried to upload photos from Dropbox and Instagram, I clicked the button in the toolbar but nothing happened. Any ideas why?
