Suppose you are writing a blog post and are looking for an image to brighten up the blog. Of course, it is easy to quickly search for an image on the Internet (e.g. via Google) and add it to your blog. This also happens regularly, but is still not recommended. This is because the image may be copyrighted and its use may result in the payment of substantial damages.
An image on the Internet (for example, Google) will almost always qualify as a copyrighted work within the meaning of the Copyright Act. This is because the threshold for copyright protection is quite low. All that is required is that the image is original and thus constitutes the creator's own intellectual creation. So it is best to assume that an image is copyrightable.
If an image qualifies as a copyrighted work, that means the image may not be reproduced or disclosed without the creator's permission.
