Photo of Baha’u’llah

Baha’is do not hang or keep images of Baha’u’llah. We should refrain from looking at His image casually and save it for pilgrimage or a few other special occasions.
No problemo.
But I went on pilgrimage and

SPOILER WARNING SPOILER WARNING

While in archives we got to see His picture. But there was also a vase with His image painted on it.
Now it was a conservative time and this image is to be looked at in reverence.
So why was Baha’u’llah painted on the vase in a state of partial undress? He is at a public bath and wearing towels. His bare torso and arms were exposed.
I am not offended in any way but was left very curious as to why that is acceptable??
It kind of goes against looking at His image in reference. Or at least just seems too casual. And when there’s only two or three official photos of Him and one of those, which was approved by his daughter the greatest holy leaf is of the greatest manifestation of God in a state of partial disrobe , well I’m just left a little confused. Confused as to why somebody would paint this. Confused as to why this is acceptable to look at when his image should be revered. And in the Baha’i faith, I believe that there are no coincidences. So when literally half or a third of the photos of the supreme manifestation are like this, what is the greater message here? Can anybody explain? Also, I started voice texting and it stopped capitalizing proper nouns. So please forgive.
