I want to sell stock photos but analyze: is stock photography worth it? Map stock photo income: per-download earnings, volume needed, competition. Calculate: if photos earn $0.25-2 per download, how many downloads for meaningful income? Show me the stock photo reality: need thousands of photos for decent passive income. Give me the stock photo math: this many photos × this earning = this income. Include: whether stock photography is viable income or just beer money, how many photos needed, and if effort is worth return.
