Adblock blocks my slider

Adblock is a program, that looks for advertisement codes that it is aware of, and removes it from the website, but it also looks for codes in the website, which are defined as ads by the rules made by Adblock developers. It is not something complicated, but common sense based on the experiences. The problem with your slider is probably that you use "ad" or "advertisement" or even "banner" as classes or id-s in the slider, but can be in the name or the path of the image, too. 

You should rename the folder where your image is, and avoid using the "ad", "advertisement" or "banner" words in your image and path names.
