Added learning resources targeted for Android regarding design of Image Loading Libraries

[laaptu]

If we are designing the image loading libraries, we could use the help of existing image loading libraries implementation. So, added a few of the video that talks about image loading libraries in Android. I found these videos very helpful in understanding different problems that are encountered while developing any image loading library and how to handle them. The reason these links are put in the actual exercise files rather than on BLOGPOSTS.MD is that it will be easier for any learner to find the relevant information easily. But if needed and if this seems relevant, then it can be put to BLOGPOSTS.MD instead of here.

Thank you.
