Random image with v:iterator.random | cache issue - typo3

Question

I try to output 1 random image with VHS (version 2.4.0) RandomViewHelper v:iterator.random.
This is my code:
{namespace flux=FluidTYPO3\Flux\ViewHelpers}
{namespace v=FluidTYPO3\Vhs\ViewHelpers}
<f:layout name="Content" />
<f:section name="Configuration">
<flux:form id="random-image" label="Random Image" options="{icon: 'Icons/Content/Example.gif', group: 'Joya'}">
<flux:field.input name="classname" label="Classname" />
</flux:form>
<flux:form.section name="images" label="Images">
<flux:form.object name="image" label="Image">
<flux:field.file name="imagesrc" label="Image" allowed="png,jpg" maxItems="1" size="1" />
</flux:form.object>
</flux:form.section>
</f:section>
<f:section name="Preview">
Random Image
</f:section>
<f:section name="Main">
<div class="random-image">
<v:iterator.random as="img" subject="{images}">
{img.image.imagesrc}
</v:iterator.random>
</div>
</f:section>
I added 3 images to test, but it always outputs the same image.
Edit: the output of random is cached. So it outputs another image after the cache is cleared.
Can I disable the cache just for this line of code?

Answer 1

The solution is to use the VHS ViewHelper v:render.uncache and creatre a partial with the part that shall not be cached. Its not the best solution as you need an extra file. But right now the only other way I can think of is to use some Typoscript, and thats also something I want to avoid.

Answer 2

Another approach is to load the image true an ajax call, this way you can cache the page, but not the random image.
