webpage not working with multiple image used in animate

hello, im creating a sample website in animate. 

i have 3 layers with action layer excluded(no problem on this part)

the three layers i have are background, buttons, content

i have 1 image in background layer. if i put the image on the content layer that i use in the background layer, the webpage runs correct.

but if i put a dif. image or more image on the content layer, the webpage is showing a blank page.

HTML 5 by the way ..thankyou, hope someone could help me with this
