Terrell Owens -- No Mo' T.O. Solo Photo

Terrell Owens can rest a little easier ... because his XXX self-pleasure pics will never see the light of day ... TMZ has learned.

The woman who was shopping the graphic photos ... and they were GRAPHIC ... tells us she's had a "change of heart" and will NOT sell the pics to anyone, for any price.

In fact, the woman says she's already destroyed her copies ... telling us, "They have been deleted and no longer exist."

The seller also admits she was NOT the person on the other side of the X-rated Skype convo with T.O. ... and claims she found the pics on a computer she bought from her friend.

"I don't personally know him and have never spoken to him."

She adds, "I don't want this to continue and it shouldn't of happened to begin with."
