Slider on Spirit Child theme not working

I have a bit of an issue, i'm building a site using spirit theme (Upfront) for some reason the slider doesn't actually view any images, i have looked through the community base and it seems that the issue is resolved by shortening the image url just to the name rather than the location, however when i do that upfront just reverts the url back to what it was, furthermore it seems i cannot delete any images on my slider.

i have enabled remote support on my website http://john.chrismachala.co.uk/
