I'm new to Affinity Photo. I publish books for authors. I have an artist who creates covers for me in JPG and PDF formats. I publish the books using a worldwide publishing company named 'Lightning Source' (division of INGRAM Publishing). Lightning Source requires the covers to be submitted using their 'template' which they send my artist in PDF format and she created the 'submittable' PDF using InDesign 9780999561805-Perfect.pdf 9780999561805-Perfect.pdfbut she no long is doing that. I need to take their template and my artist's JPG and place it (in pieces?) on their template and save it as a PDF then submit it to them. How do I do this as my artist's JPG is one 'picture' that has a front, spine, and back and the template requires each piece to be placed in EXACT locations on the template! Is there a single tutorial that would demonstrate this? Thank you.
