Ruling on a woman sharing pictures of her when she was small

A young girl is either of an age and shape that is usually
desirable to men, because she is close to the age of puberty, or she may be
small and of an age where she is not desirable. 

In the first case, when she is of an age and shape that is
desirable, 

The scholars have issued fatwas stating that it is not
permissible to look at such a girl, because that may be a cause of fitnah
and provocation of desire. 

Shaykh Ibn ‘Uthaymeen (may Allah have mercy on him) said: 

If a girl has reached an age where she may be an object of
infatuation or desire for men, then she should observe hijab so as to ward
off fitnah and evil. This varies from one girl to another. Some of them grow
quickly and look mature, and others are the opposite.

End quote from Majmoo‘ As’ilah tuhimm al-Usrah al-Muslimah 

Based on that, if in those pictures you are of this age and
shape, then you are not allowed to publish them, because publishing them
helps others to look at something that is haram for them, and may lead to
infatuation with the person in the picture. 

Allah, may He be exalted, says (interpretation of the
meaning):

“Help you one another in Al‑Birr and At‑Taqwa (virtue,
righteousness and piety); but do not help one another in sin and
transgression. And fear Allah. Verily, Allah is Severe in punishment”

[al-Maa’idah 5:2]. 

This is what we think is most likely to be the case with your
picture; they cannot resemble you as you are now unless at that time you had
reached the age at which it could become desirable to look at such
pictures. 

In the second case, if you were at an age when girls are not
desirable to men, then there is nothing wrong with looking at them, because
there is no issue of desire and no risk of fitnah. 

Ibn Qudaamah said in al-Mughni (9/501): 

In the case of a small girl who is not of marriageable age,
there is nothing wrong with looking at her. End quote. 

In al-Mawsoo‘ah al-Fiqhiyyah al-Kuwaitiyyah (40/347)
it says: 

The fuqaha’ are unanimously agreed that it is permissible for
a man to look without desire at the entire body of a small girl who has not
reached the age at which girls become desirable to men, apart from her
private parts. End quote. 

What we advise you to do is not publish your picture on your
personal page at all, either because it is most likely that it shows you at
an age at which it becomes desirable to look at pictures of women and become
infatuated with them,

Or because that will open the door to others to become
infatuated with the picture and to look for the person in it, and make the
connection between the picture and you as you are now. This involves
distractions and temptations that should be prevented, especially in times
such as the present, when fitnah has become very widespread, piety has
become weak and there is no religious deterrent.
