Did you read the next paragraph? That album with the suicide cover appearntly is a bootleg, and the pic was never intended to be seen.

"By April 1991, Dead was dead, aged 22, having suffered a self-inflicted shotgun wound to the head and several lacerations to the wrists, inflicted by a knife he had bought that day. Dead committed suicide in a house he was sharing in Kråkstad with the other members of the band, and left a note saying "Excuse all the blood"[2] Other members of the band claimed it was more extensive, also saying "The knife was too dull to finish the job so I had to use the shotgun." Euronymous was first to discover the body, and took a series of photographs of the corpse, one of which was later stolen and used as cover art for the bootleg album Dawn of the Black Hearts.
According to Occultus, who briefly took position as vocalist after Dead's suicide: "He (Dead) didn't see himself as human; he saw himself as a creature from another world. He said he had many visions that his blood has frozen in his veins, that he was dead. That is the reason he took that name. He knew he would die.."[3]
The shells used had been sent to him by Bergen, Norway musician Kristian Vikernes (aka Varg Vikernes, Count Grishnackh; ex Old Funeral, sole member of black metal band Burzum, later convicted murderer of Euronymous). Euronymous was particularly cold and opportunistic about Dead's suicide; in interviews he claimed, speciously, that Dead had killed himself due to the rising popularity of death metal, the American movement Black Metal had risen against. Hellhammer claimed that Euronymous had taken pieces of Dead's brain and made a stew, in which he had put ham, frozen vegetables, and pepper: "He'd always said he wanted to eat flesh, so he figured this was an easy way." However, Euronymous later admitted that he had not actually eaten any part of Dead's body, though he had intended to. Euronymous also claimed to have collected and forged fragments of Dead's skull into necklaces, sending pieces to those he felt 'worthy' (amongst those rumoured to be in possession of such pieces are the members of Swedish black metal band Marduk & Abruptum). Hellhammer has said he made a necklace from Dead's skull fragments as well."
Them cats were REALLY living the Black and Death metal life...crazy ass Norwegians.
