I apologize if this isn't the correct place for this question but this is driving me nuts. I'm working on a 5x5 picture cube that I was given as a present. I have all the center 3x3 pieces solved and orientated correct, with the exception of the last one. The center piece needs to be rotated 90 degrees, and UR and UL need to be swapped, but I can't for the life of me figure out how to do this, and can't find any algorithms online. If anyone has any suggestions or advice, I'd greatly appreciate it, photo attached for reference, thanks.
