Yes, it really is unlimited apps and images with any paid MyPhotoApp subscription... we don't count.
However there are 2 circumstances when you might have a limited account:
- If you have a Free MyPhotoApp account there is a limit of 20 Apps and 20 images per gallery.
- Free Apps like the Model release come with a limited account that allows you to create a maximum of 3 Apps
However, the purpose of MyPhotoApp is to produce apps to market your business and support your clients. If you are just using MyPhotoApp as an image storage dump or some other unintended uses, then that is out of scope for the terms of service.
