To get a sense of what may be shown in these images, one has to go back to press reports from when the Abu Ghraib abuse scandal was still front page news.
This is how CNN reported it on May 8, 2004, in a typical account that day:
...A military report about that abuse describes detainees being threatened, sodomized with a chemical light and forced into sexually humiliating poses...
"'The American public needs to understand we're talking about rape and murder here. We're not just talking about giving people a humiliating experience,' Republican Sen. Lindsey Graham of South Carolina told reporters after Rumsfeld testified before the Senate Armed Services Committee. 'We're talking about rape and murder -- and some very serious charges.'
"A report by Maj. Gen. Antonio Taguba on the abuse at the prison outside Baghdad says videotapes and photographs show naked detainees, and that groups of men were forced to masturbate while being photographed and videotaped. Taguba also found evidence of a 'male MP guard having sex with a female detainee.'...
The military later screened some of the images for lawmakers, who said they showed, among other things, attack dogs snarling at cowed prisoners, Iraqi women forced to expose their breasts, and naked prisoners forced to have sex with each other.
