image url
Hi , I have generated An Api key, but i don't know how to build image url..
please instruct me to build image url...

When an API Request is made, in the responses received you will find the Path of the images:
poster_path or backdrop_path or profile_path or logo_path or still_path.
Something like that:

backdrop_path   "/hZkgoQYus5vegHoetLkCJzb17zJ.jpg"   
poster_path "/r3pPehX4ik8NLYPpbDRAh0YRtMb.jpg"    

To access/download the image use the basic images URL.

https://image.tmdb.org/t/p/  

The request should be similar to these:

https://image.tmdb.org/t/p/[size]/[poster_path]  
https://image.tmdb.org/t/p/original/wigZBAmNrIhxp2FNGOROUAeHvdh.jpg  
https://image.tmdb.org/t/p/w500/wigZBAmNrIhxp2FNGOROUAeHvdh.jpg  

https://image.tmdb.org/t/p/original/wigZBAmNrIhxp2FNGOROUAeHvdh.jpg

Make sure to read the documentation around images.
