There were shared by an artist on a Facebook group. I think they seem offensive in some sense - but then I have also been told I am too sensitive and overthink everything. I also wonder if the original intention of the author matters, or the geographical origin of the pictures in relation to what is the style of humour captured.
I am trying to be more aware of when to "get over myself" so I would be interested to see what others think.
YABU - they are not offensive at all
YANBU - I can see what you mean
