Can I change the resolution on a photo I send as an attachment from the default of 96 DPI to 600 DPI

more options

If the recipient of the photos wants to print them they come out all grainy with lines through them and the detail of the photo is not good at 96 DPI, They are much clearer at 600 DPI I need to know how to change this before I send.

Thunderbird is email software, not photo editing software. You need the latter to work with image files.

FYI: if you think that you are going to change a file that is 96dpi now to one that is 600dpi and have it look good, you are mistaken. Even if that would work 240 or 300dpi is all that is needed for a good print.

I am not trying to edit a photo, I am trying to keep Thunderbird from automatically editing it when I send! Thankfully some else understood my question and gave the answer I was looking for. Thunderbird itself provides an add on that solves the problem. And yes, it can be done since I have now done it. Suggest you only try to answer the questions you understand.

I guess I did misunderstand your question. I thought you wanted the best image for printing to reach your recipient. Using some random add on and trusting it to reduce the size of an image and retain the image quality is not the way to do that. But if that works for you then you are probably satisfied with the way your images look on Facebook after they compress all the details out of them too.

Good luck.
