i used to be a flash genius.. until a few months ago. i needa make a splash
page for someone... and they want the pic to start at like ALPHA 25% and
increase to 90% when mouseover. I forgot how to do this. Please Help.

Assuming the pic is made into a movie clip called myPic.

_root.myPic.onLoad = function () {
_root.myPic._alpha=25;
}
_root.myPic.onRollOver = function () {
_root.myPic._xscale=190;
_root.myPic._yscale=190;
}

Oh, and in case you want it to go back down.

_root.myPic.onRollOut = function () {
_root.myPic._xscale=100;
_root.myPic._yscale=100;
}

i think he meant:

place your image in a movie clip symbol - give this MC the instance name
"myPic" (without the quotes).

then in the first frame of your move add these actions:

_root.myPic.onRollOver = function () {
_root.myPic._alpha=90;
}

_root.myPic.onRollOut = function () {
_root.myPic._alpha=25;
}

or you could just place the MC in a button and create a keyframe in the OVER
state and use the effects panel to adjust the alpha to "none".

either way the effect is the same. i attached a FLA.
