Thank you cards

Can you try and make your own on Canva? It is free and lots of different styles you can add your photos to and then print off yourself? We did our invites on there and is good as you can change colours etc to really make them fit your theme/ideas

View quoted message Ah, yes. I used Canva for menus and drink vouchers for the wedding. It's easy to use and I can just get them printed. Thank you!

If the photographer supplied full res images there should be no issues with quality. But if you are not using the direct image then that could be a reason. If you transferred the image to another device - via watsapp or email for instance then the will reduce the image size. What pixel size is the image you used. Look in image-info-proprieties and you should see something like 5220px X 3600px. This px number is its width and height and if this number is too small then that is your issue.
