Check the menu on the left hand side, under Media should be anything you need to upload files directly from the manager.
It doesn’t matter if you place your TV tag within a chunk or directly in the template. If you place it within a chunk, you just have to make sure this chunk is also in the template you want your image to appear.
Let me try to give you an example. Say, your TV is called imageTV. Then you can either place it directly in your template, e. g.:
// template:
<div>
<img src="[[*imageTV]]">
</div>
or you can have that TV linked within a chunk, which still has to be in the template:
// template:
<div>
[[$imageChunk]]
</div>
// imageChunk:
<img src="[[*imageTV]]">
Either way, after you select your image from within your resource, the parsed output on the front end will be:
// page.html:
<div>
<img src="/path/to/iamge.jpeg">
</div>
