File upload types?

• The app supports all types of files. Thus, you can upload any file type whether it’s jpeg, jpg, png, etc. Since this is handled by Shopify, the file gets converted into .webp regardless of the file type you upload.

Files location or Image uploads by customers?

• All images or files will reside on Shopify's servers. A link is automatically generated to the file location. A downloadable link will appear in the cart and the email confirmations.
