How do I create a photobox for image? Can anyone please guide me on how do I create a photobox that contains image and I wanted to display that image on landing page.

I have created content type as an Image. But, I don't know how to display that image in landing page. 

I am new to Drupal. Any help will be appreciated.

Thanks!
First of all: welcome to Drupal :) But then I right away have say sorry, but I think it's not really a good idea to ask people to "guide you on how to…". People here try to ask straight questions and give straight answers – if they can.

About your actual question: for displaying a specific page as your front page a.f.a.i.k. all you have to do is to go to Configuration > then Site Information > then you can adjust the Default front page setting by entering the path of any of your pages… Hope this helps…? 

And last but not least I can just recommend you spend some time with some basic recources and tutorials – for example Drupal 7 – the Essentials is sheer greatness! And the Community Documentation has almost every important aspect of Drupal listed, that one could need for a start…
