Do you have all necessary updates?
I use a different method for mouseover effects, maybe this can help:
Insert the first pic normally in page view. Include the second picture in your assets.
Now klick on the first picture an add the following code within tag:
Code:
Code:
name="button1"
onMouseover="button1.src='../assets/images/button2.gif';"
onMouseout="button1.src='../assets/images/button1.gif';"
button1.gif and button2.gif being the exact file names for my pictures as an example - but you would use yours instead.
If your action is used on your "Home" page, please remove one point from the link: ./ instead of ../
Hope this helps.
