Regarding the Adsense feature: The idea is to allow gallery users to monetize their flickr photos on their site in an elegant way with responsive Google Adsense ads places seamlessly into the gallery.
This is basically not a problem as I have understood Matt Mullenweg posted on the www.ads-software.com support forums:
There are plenty of plugins that tie into third-party services, for example Google AdSense, and some of them have no free versions. That’s totally fine as long as the plugin is totally GPL.
I have now double checked the plugin guidelines and found that:
If the plugin does include advertising from a third party service, then it must default to completely disabled, in order to prevent tracking information from being collected from the user without their consent. This is the method commonly known as “opt-in”.
Version 1.0.0 and 1.1.0 are not compatible with that requirement. I’ll disable the Adsense feature by default as required by the guidelines. An updated version 1.1.1 with “opt-in” will be available asap.
