Use the embed image feature.
If you are looking to increase your Instagram followers and your blogging crosses over in terms of subject then there is a simple function provided by Instagram that can help.
Rather than add an image directly to your blog you can embed them from Instagram, read how via the Instagram website.
Nothing more complicated than that, readers can then pop over to Instagram simply by clicking on the image and you still get the benefit of displaying your pictures on your website.
