People seem to be downvoting the following bear's arms crypto community ad:
Here's the ad, which is exactly 220x250, with Retina support:
The primary reasons for downvotes given is that the image is 440x500 instead of 220x250, which it is not — it's just a Retina one instead.
Is this really a problem? Do the rules really meant to prohibit Retina support? Must one drop Retina?
A secondary reason given is that it's not "GIF or PNG" — it is JPEG instead.
Is this really a problem? Should one convert this photo to a GIF or PNG?
Additionally, someone managed to find a third reason — ad contains a CC-BY-2.0 image of a lovely bear with cute arms. This someone claims that it cannot be used in the ad once shrank to 220x250 non-Retina pixels.
But I disagree — it's used the same way on http://en.wikipedia.org/wiki/Bear (and in Google, too), without any credits, unless you click on the image and perform extra steps.
My understanding is that each ad has a link back to the voting page (if you hover over the ad once in circulation), thus that could remain to be the only place where the credits are given. Is this line of thought incorrect? Must a different image be found?
