Mail: image attachments turn to thumbnails when accessed on a pc
Firstly I am aware there has been, for a long time, 'issues' with attached images being inline on windows. However, this is a new issue for me and I am struggling to rectify it. All images I attach in emails sent using Mail are shrunk to a thumbnail when open in windows. I can compress and send and this is a work around but if someone kind person can explain why this is happening and offer a fix I would be very grateful.
Thank you.
