I'm not sure what your use case is so maybe this isn't helpful, but Wikipedia has weekly or so database dumps that you can download, as well as static HTML (although that might be more out of date)
Kiwix has a mobile app that runs a local copy of full Wikipedia (~80GB) from the device, with formatting and pictures and everything. I'm not aware of any other fully-baked solution that does this.
It looks like the pictures are not available as a dump from Wikimedia; the page you link to implies that they are, but the latest dump is from 2012.
