Yeah, I've had iOS friends tell me that I didn't send images "as photos" because it didn't show up in their photos app when they download it, and that they needed me to "send it as a photo instead of a file". I'm like my brother in Christ, it's a jpeg, just figure out where you downloaded it to. Apparently it's confusing getting image files that weren't automatically imported into the gallery into the gallery, because it's typically seamless or something. So when they download a jpeg a certain way instead of having it sent on iMessage they get lost.

I've also had friends on iOS tell me that iPhones can't open zip files, and I'm like surely that's not true.
