Were they written on a Mac originally? I’ve seen a similar message in the Officeworks photo machines - can’t read the files, but they can read the same file when it’s been emailed.
A friend had a similar issue with his TV - the drive was formatted in whatever the latest format is, but TV could only read FAT.
Snipped from another site, I didn’t link the site 'cos it is full of pop up shit.
"If you need to expand your storage space with an external hard drive and you use both Mac and PC, you’ll likely run into a few obstacles. Hard drives advertised as being compatible with Windows and Mac OS may have misled you into thinking you could actually use one hard drive for both computers.
You can, but not out of the box.
Most external hard drives (HD) are sold in a format called NTFS, which is designed to work with Windows. Macs read and write to a different format, called HFS+. Another format, called FAT32 is compatible with both OS platforms. Here’s a look at how the different HD format types function:
FAT32 (File Allocation Table) - Natively read/write FAT32 on Windows and Mac OS X. - Maximum file size: 4GB - Maximum volume size: 2TB NTFS (Windows NT File System) - Natively read/write NTFS on Windows. - Read-only NTFS on Mac OS X - Native NTFS support can be enabled in Snow Leopard and above but has proven instable. - Maximum file size: 16 TB - Maximum volume size: 256TB HFS+ (Hierarchical File System, aka Mac OS Extended) - Natively read/write HFS+ on Mac OS X - Required for Time Machine - Maximum file size: 8EiB - Maximum volume size: 8EiB"
I emailed the photos to him. He received them and can see them, but can’t save them “because they’re in the body of the email, not attachments”.
No one I know has ever had this problem, and as far as I know it’s the only way Mac sends files. It’s years since I used Windows (thank goodness) but I thought there was something on the toolbar like “Save attachments” that would do it. He’s using Windows 10.
What does he need to do (apart from “Get a Mac”).
I’ve seen it before - usually the Win person is completely unfamiliar with the concept of drag and drop! I would have thought he could right click on the image and “Save As” but anyway… do this on your Mac:
Go to the Edit menu in Mail. Scroll to “Attachments” then select “always send Windows friendly attachments”
Oh yes, if his computer is still being a dick about it, there are a couple of other things you can do:
Drag and drop them onto your email. This usually works whereas selecting them from a file or direct from Photos embeds them differently.
Or if there are a few of them, plonk them in a separate folder and compress it,(Finder File menu) then send the compressed file.
I presume it’s whatever comes bundled with Windows
Never ‘presume’ or assume anything…
No mail program comes bundled with windoze any longer.
MS want you to use web mail or buy a copy of Outlook.
If you know how, you can still download MS Windows Live Essentials & get a free mail client that way but it is now 5 years old & I personally f’n hate it.
(It also comes with a boatload of other useless shit that MS can’t sell 'cos nobody is stupid enough to pay for it.)
There are other free/shareware mail clients out there but they don’t come bundled & all have their own inherent weirdness.
Can you ask him what he is using?
