Can you transfer iphone photos to a digital polaroid camera through SD card?

Photos from my phone do not seem to appear on an SD card when inserted into any camera.

Both images on the SD card are JPG from my iphone and my camera (my polaroid reads JPGs from other cameras but not iphone photos) I was wondering if there's a required size or procedure before a photo is able to be printed.

I have an iphone 5c
I have a digital polaroid camera that uses an SD card and that cost a lot of money and that is massive so I do not want to lug it around all day, there are also some meaningful photos on my phone and I would actually like to use my camera!

I also want to point out the photos taken with Polaroids are incredibly bad quality so I'd rather use another camera and transfer them over (and it was a present I know I could have just bought a digital printer I feel bad for not using it) (I'm going to stop justifying myself now)

Doesn't work like that. The file properties do not match - the camera is not intended to be a display device for images generated by another device.

Why would you want to put other photos on to your camera! It's way better to save them on your computer where they will be safe, virtually forever.
In any case, I'm sure it's not possible to do what you are trying to do because the file formats are different.

Yes but there's no guarantee the pictures will show up.

Cameras are not viewing devices in case you still didn't realize it yet.

If all you need to do is to bring the pictures to someone who can print them then yes, the pictures will be safe in the Polaroid's SD card unless someone accidentally deletes them.
