Maybe yes, but I wonder what's the photo is made of. Anyway, I think that the pen and even the flower are mightier than the sword. Well, maybe they are not strong like steel but they are good: you can be stronger than the steel but if you're thought is bad, then you're strongness is nothing, futile.
The pen is mightier than the sword and a picture is worth a thousand words.
If there was a picture of a pen, is it much more mightier than the sword? What if picture depicts a pen and a sword? Does that mean the metaphor "the pen is mightier than the sword" has reached its ultimate glory? What if the pen drew a sword on paper? Does that mean the pen is subject to its own faults? What if the sword drew a pen on the ground? The sword is the sole reason why this metaphor exists?
Get the literal out of it and keep to metaphor. Also attempting to chop a pen up with a sword could cause damage to the blade depend on its construction, part of why historical swordsmanship doesn't have blades touching each other in a fight.
I know swordplay in movies and other media portrays that but that is not historic swordplay, still there is stabbing, there is a word i've come across in german that specifically means having your lung collapse by a sword piercing. And there is also dueling scars
Pen is mightier than the sword as written word is more likely to make an impression on larger group of people. However if we base our assumptions upon pen's might being those of written words then we may compare picture and pen. While picture is worth a thousand words, pen may also produce those thousand words and more. However I would say picture does better job transferring certain type of language faster than written words. However the language used on written words and pictures is by nature very different and one can't completely ever replace another.
