My images are appearing broken

Known issue at:

- 8 bit, PNGoo

If your images aren't appearing correctly, like there is only one color on the whole image, while in your server the original images look fine, then this is happening, because of the Optimize option, which is resizing your background images to the size of the slider, just this optimization option doesn't work with specially compressed images, so you should turn this option off, and it will be fine!
