Partners purchasing the share of a partner

Q: There are 3 partners in a business (2 active and 1 silent). The one active partner wishes to exit the business. The share will be paid off through the business over a period of time, not any external funds.

Will it be permissible for the 2 remaining partners to mutually agree that the share of the exiting partner will be purchased only by the active partner or is it compulsory for both partners to purchase this share equally?

Income of a person who uses pictures of animate objects in his presentations

Q: My father works in an office where his work is to maintain proper supply of electricity, making and maintaining electrical plants and supervising others who do the above works. Part of his job is to inform his seniors about new plans and progress of the plans. For this purpose he uses digital slides for presentations.

I noticed that the slides that he makes, he uses pictures of animate object. It could be a requirement from the office that he must use those. Sometimes others make these type of slides and he uses them. And sometimes he makes these slides and passes it to others. I want to know, does it make his income haraam?
