The internet has become 3 massive multi-user blogs, each largely consisting of screenshots taken of the other two. This kind of blows, and not just for the usual reasons that may spring to mind.
Images are a terrible medium for online communication! Not everyone online uses a monitor. Any messages contained in a picture is straight up unacceptable without alt-text. It also makes it harder to find and fact check sources, or to spread a thought or idea further than yet another image upload. Copy/pasting text is just plain easier than downloading and uploading.
If you're going through the trouble of creating an image post, take an extra minuite to copy/past (or even transcribe) the source text into the alt-text submission. It's not much, but it goes a ways to improving how we use this blasted network!

on desktop the button between upvote and reply is "view source" and shows you all the markup including any alt and title text.
Haha, yeah, sorry, that wasn’t super clear, but I meant in cases where there isn’t a view source button, which on mobile is most images on the internet, and on desktop depends on whether you consider reading HTML an “easy” way to see alt text.
