How can i add images from my gallery using HTML5 ?

Answer 1

To insert images present in your phone or pc, write the following syntax <img src="///(file path)\(file name).(image format eg: jpg, png and so on)" />

If your code is in sololearn, this won't work.

Answer 2

You can't really do that.

Maybe you could use dropbox or something.
But, normally you wouldn't be able to do so
