Like this one: meh.ro I don't know if they are using Adsense. But let say if one make a similar site will there be any issues with Adsense ?
No I don't recommend doing that. As soon as your site gets manually reviewed they will ban it from the AdSense program and it will all be for nothing..
tbo I'm sure I've seen websites with images only showing adsense. You could write a script to rotate text.
Ive had websites with just images on them, with minimal content, and still do, and have not been penalised or banned by google thus far..
I have also talk to a couple of people with meme sites and they have been using adsense for over a year.. But I have a image site and i use another network, just to be safe..
I can't suggest as I just started my image site. So still searching and since traffic is still not enough..
As far i read the google adsense guideline at - https://support.google.com/adsense/answer/48182?hl=en there is nothing such things being said that you should not put ad on only image sites.
I have seen a lot of sites which expose images with very little content. And yes there is no such things that disallow images only sites to participate in the program. As long as the images and content follow the google rule, it is okay.
