Every website or blog uses thumbnail images, it’s a very useful part of the website.If you don’t see any images or thumbnail you quickly skip the website or article. You wont read it in deep but if you find few thumbnails between or in start of the News or article you would like to read and stay more on the page or article. It’s human nature visual images attracts mind rather than just bunch of words, isn’t it?

TimThumb is a small php script for cropping, zooming and re-sizing web images (jpg, png, gif). Perfect for use on blogs and other applications. However TimThumb is no longer supported or maintained by its developer as TimThumb has a major security exploit found and it hurts lots of website. In result They dropping all future support and maintenance for TimThumb but I will still suggest to give a try to TimThumb but don’t use it with WordPress. you can find the major issues at https://www.binarymoon.co.uk/2014/07/dont-use-timthumb-instead/
