High-resolution Creative Commons badge

Thursday, October 26th, 2023

I noticed that the pointers tutorial‘s Creative Commons badge had gone missing. I guess they got tired of people hotlinking it.

So I grabbed it from the Wayback Machine, and when I did, I noticed that it’s in the classic 88×31 format used by so many miniature promotional images. If the phrase “Netscape Now!” means anything to you, you know what I’m talking about.

There’s been a growing trend of making new 88×31 images, some in higher resolutions for modern hi-DPI displays. So I thought I’d do one: redrawing the classic Creative Commons bug as a vector image that could be exported as SVG and as high-res PNG.

Here you go:

The Creative Commons logo on a gray field, with “Some Rights Reserved” in white on black beneath it.
The double-resolution PNG.

The SVG.

I think the original image falls under the CC-BY (Attribution) 2.0 license that was then current. I’m happy to place these new images under the same license or the newer 4.0 version.
