Porn pictures of George Bush and Paris Hilton go on show

Hi CJ that's exactly what the portraits are made of "porn pictures" taken from pornographic magazines. I was wondering in what way, or who, the use of the word 'porn' to describe pornography degrades - if you could give me some other word/s that means the same and describes the pictures used I'll consider perhaps using them.

Yeo is a brilliant artist - his paintings in oil of Blair and others are wonderful - and his use of pornography cut from pornographic magazines to then construct portraits is I feel important work. Here's what the Independent said (note the use of the word pornography):

"Yeo appears to be throwing aside his mantle as the establishment painter of his day (he's created portraits of Tony Blair, Margaret Thatcher, Dennis Hopper and a litany of other celebrities) in favour of something that has more in common with the language of revolt. His brand new show of collages is made exclusively of pornographic imagery and grew out of a print he made of George Bush with cocks subtly inserted in his face. This exhibition of contorting nudes, and portraits of people like Hugh Hefner, is made exclusively out of cuttings from the cheapest magazines to be found on the top shelf. The results are surprizingly thought-provoking."

what is that suppose to mean bill?
