Changing the Logo Link & Changing Image Sizes for the Layered Slider?

Hi

I’m new to WP, so these may be dumb questions, but I just can’t seem to figure them out.

I’ve uploaded a new image to replace the Enfold logo, but every time I click on it I get sent back to the dummy page or whatever the standard Enfold page is. How to I change the hyperlink, so that when I click on the logo it returns to my new Home page every time? I rather people click on the logo than build a Home button.

I also can’t figure out how to make my layered slider look like the dummy example. My photos are imported to my computer in all different sizes and resolutions, but I want them to fit the same way I see them in the dummy slider. Either they get cropped or are so large I have to scroll quite a ways to see the image in its entirety. Is there a standard size they should be in order for them to look like the dummy example?

Any help would be appreciated! Thanks!
