Help Needed: Using a Slider to Rotate a 360-Degree Image in Storyline 360

I'm not exactly sure what exactly you mean by 360-degree image, as they are variations, e.g. an image imported into Storyline or a rendered animation from some 3D software. In the past, I have worked with 360-rotated device images. If you have the option to export your 3D image as individual bitmaps, you could add them as states of a Storyline object and then change the object state based on the slider variable's value. See these old example here (examples 4-6) https://dev.keypointlearn.com/xcl74_SL3/DialsV1x/story_html5.html This was done with dials, but the concept is the same.
