[FONT=Times New Roman][SIZE=3]Hi[/SIZE][/FONT]

[FONT=Times New Roman][SIZE=3]There is a great tutorial under the topic Flash MX2004 – “Adding thumbnails”.[/SIZE][/FONT]
[FONT=Times New Roman][SIZE=3]It’s about how to make a photo slideshow with scrollable thumbnails using Flash and XML. And it’s function is simple too, just click on a thumbnail and larger image fades in above.[/SIZE][/FONT]
[FONT=Times New Roman][SIZE=3]If photograph is taken as landscape everything is fine but if it happens to be upright or portrait, it appears on left side of the picture_MC. [/SIZE][/FONT]
[FONT=Times New Roman][SIZE=3]Is there any way to make upright images appearing in the middle of picture_MC?[/SIZE][/FONT]
[FONT=Times New Roman][SIZE=3]Here is the code.[/SIZE][/FONT]
