That is a false assumption

Another false assumption
Perhaps worldwide it's a false assumption, but when someone puts up a request like this, they're usually referring to their userbase, and they're likely going to know if most of their users are browsing with smartphones (based on analytics or just based on users telling the staff).
Phones are for making phone calls
Cameras are for taking pictures
Computers are for accessing fora
Well, when you have a smartphone, you have a computer, a camera, and a web browser (by default). A smartphone fits many roles that would traditionally require multiple pieces of equipment. Because it has apps that provide the functionality, a smartphone is a camera, and is for taking pictures; a smartphone is a phone, and is for making phone calls; and a smartphone is a browser, and is for accessing forums (and other websites).
Sure, some people have flip phones that only do voice and text. Some people have smartphones and only use it for the former two uses (which imo is a waste since you can get by just fine with a flip phone for much less cost, but I digress). Some people have smartphones and only use it for dedicated apps, rather than web browsing. Other people use their smartphones and tablets for all sorts of things, including web browsing, and including forums.
So it's a bit unfair to dismiss his post as "false assumptions" and based on your personal experience, when really it's his forums' users' experiences that matter in terms of the request he's made.
So with that in mind, here is an extension I found fairly quickly browsing through the Customisations Database. It doesn't do exactly what you're wanting, but it should help with keeping those huge images from taking up all your server space. https://www.phpbb.com/customise/db/extension/tinypic/
Basically, it embeds an upload form for TinyPic, an external image host, and allows them to upload and get an embed code/URL for their images, which they can use to show their images. This would work differently than the current attachments, but as I said, it would keep the large images from taking up your server space, and would keep your members happy because they can still upload their large images.
