I used the URL - http://appsinmotion.in/htdocs/images/turtle.png - gives the error 404 Not found. Please help me immediately.
I can see the image files in file manager
But unable to access through URL
your URL must be without "htdocs"
htdocs is root of your website = http://appsinmotion.in
your brain did not make a mistake (you used good logic)
You saw that when you opened a file manager you have to go inside of htdocs folder
And for you this is a just one step deeper into the hierarchy
but htdocs directory is created to put stuff which will be available online
and in that way separated from other "more serious and private things"
