Email Photos

[Meanie]

I often take pictures using my iPhone then send to my email, using
Outlook, of course. When I open the email to view the picture, I click
on the photo file which opens the photo gallery. There, I can usually do
some minor editing such as rotate and save. The files are coming in as
"Read Only" and I must click the properties to unclick the read only
box, then I can edit. On another computer, I don't need to do this. Is
this issue within Outlook or within the photo gallery I'm using to open
the photos? If in Outlook, any insight to resolve? Of course, if it's in
the gallery and you know how to resolve, I appreciate that also.

Thank you.
