I work as a web designer. This profession involves the displaying of human images (male, female) and insertion of music and sound loops in websites. Now as a profession, I want to know if the money i earn from this source is haraam or halal? I've spoken to few people and they told me, the least rank of thought is to make sure that I'm not involved in 'making' those images and music. I only take sources given by my clients and in some cases take existing sources available on the internet and display them. So, please let me know of this issue. Jazakalah Khair.
