Photos do not show in Messages - Only show as image filename
For a long awhile now on Messages has not been handling images sent to me properly.
All that shows up on Messages on my MBP (now running Yosemite) when someone sends me a message is the image filename (example: IMG_0456), with a little Preview icon to the left.
Before the image used to show up on my Messages app on the MBP. Now, even clicking to open the image filename, just brings up a little dialog box with a larger Preview icon and the size of the image.
In order to view images sent to me, I have to check them on my iPhone.
I was hoping the Yosemite upgrade would fix this, but it seems to not have, and numerous searches for answers brings up no results. I have no idea when this started as it happened awhile ago.
MacBook Pro, OS X Yosemite (10.10)
