Slider Autoplay & Avatar Problem

Hi,

I have 2 problems on my website using your Blackfyre template.
– I would like to set an autoplay for the slider on the homepage. I mean each slide is display during some seconds. Do you have any advice ?
– I would like to know which part of functions.php I have to modify in order to display the image upload by the current user on all the pages of the website. I deleted the folder with the avatar by default (http://team-1up.fr/wp-content/themes/blackfyre/img/defaults/default-profile.jpg) so all images are broken for the moment (just the time to found a solution).

Thanks for your help.
