Control TV from one place in all template

I have a sidebar with Slideshow - a slideshow that is set in the Chunk and includes TV:

<ul id="slides">
<li><img src="[[*SideBanner1]]" alt="[[*TextBanner1]]" /></li>
<li><img src="[[*SideBanner2]]" alt="[[*TextBanner2]]" /></li>
<li><img src="[[*SideBanner3]]" alt="[[*TextBanner3]]" /></li>
<li><img src="[[*SideBanner4]]" alt="[[*TextBanner4]]" /></li>
</ul>

Everything works nicely if you take the time and on each side add photos and descriptions via the TV.

Question:

How do the user change images in one place and change everywhere, not to be introduced on each side especially.
Like, if you set in TV to default value.

Thanks for answers

you can create one extra - Resource where you manage your slides and get them with
getResourceField one by one or with getResources.

But you can also create the slides-gallery in that extra-resource with MIGX and call them on each page with the included snippet getImageList and the docid-property from that extra-resource.
