Blur image slider

Hello,

I tried to copy "demo-resume.html" and just change the slider-image. After I changed the image and added all neccessary css files the slider is working for some part. I have tried two things: 1) just change the image, the blurry effect don't work at all 2) add a blurry image to the normal one, this version funcionate perfectly except when i open the website the image is blurred until I scroll.

...

Side note: I changed the header and the menu, I copied that from "demo-photography".

Can you give me a hint about that issue?

Thank you very much in advance!

Also the link "My Works -->" on the original file from "demo-resume.html" is working at the beginning. After some scrolling on the page the link seems covered up and is not clickable anymore.
