In this article we propose a modified bit map image hiding method which utilizes run-length information and an additional bit value for enlarging hiding capacity. A run-length approach for image steganography was firstly proposed by C.C. Chang et al. They have shown that the approach earns high capacity for secret data containing long runs of repeating bits. By our modification, the hiding capacity of proposed recipe almost doubles the original one at most and results equal decrease about the PSNR criteria.
