Also please use any image of your choice for the sub-menu mock ups and I can change or update it later.

Hello,

I changed the pixel sizes but it still wont let me load the logo

I am also not able to create my website as it is was shown in the Demo i.e. with the large images on the home page which are animated/slider and with the smaller images which I believe can be used as sub-menu items

I would be very grateful if you can explain how this can be done.
