Dear Ben Point taken as regards the ruby versions discrepancy.
I was able to solve the problem with the help of heroku support personnel. There were two issues: One issue with the image_tag options syntax... This prevented the asset pipeline to reference the image filename with the harsh extension (the long file name created by asset pipeline). Once, I fixed this problem, the images could still not be found due to the fact that they had JPG extension in capital. A photo editing program had turned all the extensions jpg in capitals. This did not cause any problem in the development environment, but caused problem in the production environment with images not being found. Besides, everytime I changed these extensions back to small jpg, the git local repository would not take these changes into account. Very strange indeed. I ended up recreating a new git repository and redeploy the app with all pictures in small jpg extensions, and then it worked. Thank you for taking the time to respond to my query.
