What is the ruling on sending photographic images for sponsoring orphans from one country to another, and is it permissible for money, and does it fall under the general prohibition of imaging found in the hadith?

Photographing an orphan and sending his picture to someone who wishes to sponsor him, and placing photographs on currency, are subject to scholarly disagreement regarding the ruling on photography. The relied-upon opinion is to prohibit what is not necessitated by need. Placing pictures on currency is not necessitated by need, and photographing an orphan is best avoided to steer clear of doubts. Benefactors can be encouraged to sponsor him by reminding them of the reward for sponsoring an orphan. However, if the pictures on the currency are drawn and not photographic, they are more severely prohibited.
