Hey @Aray!
I'm not sure it's possible to include images inside an email body in Retool. We also don't have any PDF editing capabilities just yet.
Here are some links to attaching images in general:
https://docs.retool.com/queries/guides/emails#add-attachments-to-emails
https://community.retool.com/t/how-to-send-an-attachment-in-e-mail/7767
And in case it's helpful, you can download a Retool page view as a PDF using utils.downloadPage():
https://docs.retool.com/reference/apps/global/methods/utils#utilsdownloadpage
I'm sorry I couldn't share a more helpful answer, and please do let me know if you have any questions!
