When clicking on the thumbnail image to get the full size image, the label at the bottom (with controls to view the prev/next) seems to include the total number of steps but with no of between them, which just makes the label confusing.

This is a bug in the current implementation (there is also a separate, larger enhancement for this label/control in elastic/uptime#291).

For example, clicking on the thumbnail for step 1 of a 9 step UJ:

I would suggest the scope of this fix is just to add of between the current step number and the total number of steps.

@katrin-freihofner are you ok with this more urgent fix, until we get elastic/uptime#291 done?
