Hotlinking Images? No. Wget Instead.

Submitted by aaron on Fri, 2008-02-29 12:10

There's an open feature request for the Embedded Media Field to allow editors to link to a live image on any arbitrary site. Although this is technically possible, and easy to implement in the module's framework, this practice is also known as hot-linking, and I'm not particularly interested in enabling that sort of functionality.

However, the discussion on that queue did lead to another interesting possibility. Using file_get_contents (or maybe more efficient method?), I can 'wget' an image and store it to the server. Then the image can just be served locally. I was already examining that possibility for storing (YouTube, Blip.TV, etc.) video thumbnails as well, so I should be able to sign off on two tasks with this mini-project.

It opens up the possibility of copyright violation, but I leave it to the lawyers to fight over that one. And though there are certainly some cases where a hotlink implementation might be okay, I'm personally not interested in encouraging that.

The Society for Venturism has chosen me as the recipient of its charity for this year, to hopefully offer me cryonic preservation when the time comes. And this month, Longecity, an excellent forum for the discussion of issues related to extending the lifespan of humans, has offered up a matching grant of up to a thousand dollars to help out! So help out! Please.
