What does the "last bits of image" mean when the image is RGB, which is composed of three gray scale image planes (color channels)? And where did you post your images? You forgot to tell us.

I'm not a steganography expert, and I don't think any of the regulars here are. So I suggest you find a method in VisionBib in one of these sections:
23.3.8 Image Hiding, Data Hiding, Steganography, Steganalysis
23.3.8.1 Data Hiding, Steganography, LSB, Least Significant Bit
23.3.8.2 Halftone Images, Compressed Images: Image Hiding, Data Hiding, Steganography
23.3.8.3 Surveys, Image Hiding, Data Hiding, Steganography
Then we can help after you've made an attempt at coding up your chosen algorithm in MATLAB.
