You can do pretty much anything as long as it is for your own use. For example:
- making cards and invitations, once print them out, you can send them to your friends and families.
- create a art print, print out and hang on the wall, or give the print to your friends and families.
- edit images and use them on your website and social media as long as the files have been flattened and the file size has been reduced to screen resolution, hence the original files can not be downloaded.
The things you can not do:
- give away digital images away to anyone else.
- upload the original images the internet, hence can be downloaded by others.
- making artwork for sale.
