If you sum up the roman numerals on the clock (1 to 12), you get 78, but the clock on the image has a drawing shaped like a D (500) in its center. So all the roman numerals on the clock sum up to 578.
That is really clever 'PotatoBoy'......... but no cigar this time....... there is a relationship between the image and this challenge but only in the use of letters.
