Hi Vivek, Your workflow sort of reminds me of http://xkcd.com/763/ :)
First of all, make sure that you find a way with a minimal number of operations. Every time you do something, you may negatively influence the image quality. Also make sure to always use PNG format for intermediate stages, only writing a JPEG (if necessary) at the final stage. Then, please realize that Powerpoint is not an image processing tool. It's as good for that as Word is. You really need to use an image processing program like the Gimp, Photoshop, Inkscape or Coreldraw. The first of these are pixel based (bitmap) image processing tools, which allow retaining the quality of the image, whereas the latter two are vector based drawing programs, that are specifically equipped for adding labels, arrows and such, while able to import and export bitmap image files. Importing bitmap images in these will retain the resolution and you can specify the output resolution of an exported image, allowing you to accomplish what you want. Alternatively, you can use the vector programs to make an image mask with a transparent background that you can lay over the image using the Gimp, Photoshop, or Imagemagicks convert.
