Fade and light images

I like this code, but what I don't like is how dark it looks. Anyway I can make it slightly brighter before someone roles their mouse over the picture?

This is the part you have to change for the lightest or darkest:

Code:

opacity:0.7;

Okay, is there anyway to make the homepage buttons , Home, FAQ, and search ect back to their original brightness?

Search in your CSS ( ACP > Display > Colors > CSS ), this code:

Code:

a.mainmenu {
    opacity: 1;
}
a.mainmenu:hover {
    opacity: 0.60;
}

And delete the opacity value. You can change the value to "1" for 100% opacity and the 0.60 por add opacity.. It will be with a decimal.

0.90 = 90%
0.80 = 80%
0.70 = 70%
Etc
