If we use any multimedia link in HTML or another language projects, is there any copyright issues?

Answer 1

It depends, you should check the license of any external content you want to use.

On Google Search you can filter the images that comes with a "free license" or something of a kind, just to avoid copyright issues.

You can also make use of services like unsplash to avoid copyright issues while getting HD images.
