If you are developing an application/website and it doesn't work with 50% of your market share- then you are a dumbass for not implementing it.
ESPECIALLY for an AP EXAM with consequences.
This isn't like "oh no, 50% can't reach our site about cat videos". This is an EXAM.
Honestly cannot believe people on here defending them not adding simple image support for 50% of the testers...
Apple should convert to JPG or PNG when exporting the image to anywhere anytime.
The same problem happens with webp images too - totally unusable almost everywhere, even in photoshop.
Apple wants to reduce storage space photos take up. Fine - but they should convert back to a standard format when exporting the image to be used on some other system.
With that said, it seems the issue is from students that didn't upload the image from their phone (where Apple correctly converts to JPG), but rather transferred the image to their computer, then uploaded into the AP Exam.
If that's true, then this is absolutely on Apple. Why would they export in a format that literally nobody else supports. What are these people supposed to do with a folder full of HEIC formatted photos, that can't be uploaded anywhere else, edited with any program, or opened even opened on some Operating Systems?
Apple should assume nobody else uses HEIC because... well, nobody else uses HEIC.
JPG and PNG are here to stay. Love it or hate it... they are the lowest common denominator for image formats.
New formats are a good thing, and fast adoption of them is good for users.
Samsung have started changing over as well, it's the default on their latest phones.
So is COBOL[0]; that doesn't mean you should ever use or support it.
And it you want to talk about incompetence, I'd say pushing a format that is almost guaranteed to be incompatible with the millions of existing backends out there is profoundly stupid.
