Need help with photo gallery

[font=Trebuchet MS]Hi[/font]

[font=Trebuchet MS]I am trying to make a photo gallery but I have run into some problems. I want to have a page with thumbnails on the left side and a display area for the large images on the right side. The thumbnails should be black/white in the ‘up’ state and oloured when rolled over (this much I can do). Then when a thumbnail is pressed I want it to remain coloured and on the display area on the righ I want the large version of the image to fade in. This is where I have my problem.[/font]

[font=Trebuchet MS]I have made a button containing a MovieClip (to do the fading effect), but I can’t understand how to call it. The movieClip contains a frameLabel called [color=blue]play [color=black](starting the fading)[/color] [/color][color=black]and then I would figure that I’d have to call this label, but I am not sure how to.[/color][/font]

[font=Trebuchet MS]this is the AS I have (on the button):[/font]

on(press){
gotoAndPlay("play");
}

[font=Trebuchet MS]but that doesnt seem to do the trick. Do I need some kind of DOM like this.gotoAndPlay…?[/font]

[font=Trebuchet MS]Also I have realised that the filesize is huge with all the images so how do I load them individually (so that the image isnt loaded untill the thumbnail is pressed)?[/font]

[font=Trebuchet MS]Any help would be greatly appreciated :)[/font]
