image delay in mouse over...

[yaniv]

i use attribute.add to add a diferent look to my link when the mouse in over. the problem is that their is a delay in the chane of the image. i want to add a preload of the images, but i can't find the way to do it from the code behind, how do i put the images as var, and call them from the code behind, i don't want to use java script in the html page, i want all my function to be in the code behind... can it be done?

You can use RegisterClientScriptBlock() to insert the code to pre-load the images

but how do i call it?

i mean, when you preload a image you use a variable to keep it, if I use a javascript, the code behind will not recognize this var as a source, didn't it?
