I have the following strange issue: I have the Supplier Quotation Doctype with a custom print format, which contains embedded images (all of the public uploads). On print > PDF, the pdf is rendered without any issues including the pictures.
However, if I send the document using Menu > Email, select to attach the print format, send it, it is received as pdf without images. What could be wrong? site_config.json contains the correct hostname. The system is on ERPNext v12.1.1. The system can access the image resource.
Thanks for any hints!
