Mysterious email image problem
After recently upgrading my iMac to Yosemite I can no longer see images sent to me from my CCTV system. This worked perfectly within Mavericks. I can still see all the images on my iPhone/iPad. The emails received from the CCTV now just display a ‘?’ instead of an attachment. Even if I try and save the image to the desktop, it won’t open… Spencer Grogan This is an odd one. CCTV systems just send image attachments as JPEGs, so there’s no unusual or legacy codec at work here. Yosemite thinks that the JPEG image is corrupted. This offers a clue; the CCTV image files all seem to begin with an underscore, and the screenshots had names of the form screenshot. 12.26.51.jpg. Removing the extra dots in the timestamp of the screenshot files reportedly allowed them to display again. I haven’t been able to duplicate the problem, never mind the fix, but it’s possible that a bug in Yosemite Mail is causing it to incorrectly parse file names in some circumstances, so that it doesn’t realise they’re image files, so tries to open them in another way. A workaround? Use another email app, like Mailbox (mailboxapp.com) until this is fixed.
