Hover Fade out/ Fade in - CSS help

[telmotype]

Hi there everyone!

I'm trying to make a fade out fade in hover but I've been back and forth and it's not working as expected.
The project thumbnail image is fading out on hover but it's not fading in as soon as the mouse leaves the hover area.
Here's the CSS I have:

.ph:hover {
opacity: 0;
-webkit-transition: opacity 350ms ease-in-out;
-moz-transition: opacity 350ms ease-in-out;
transition: opacity 350ms ease-in-out;
}

And here's the link:

Thanks!

Hey, maybe you tried it before, but did you look at that?

I did it on simple image, I remember it was working. This part is working for link images so maybe also thumbnails?
cheers
