SOme help please

I'm so new to flash, i'm using Flash MX and i want some help.
The problem is that i already have flash inside my website, i want to add or delete but i don't know how.
i understand the the flash in the website is .Fla so i can't update or add something unless i have the origin .swf right?

OK now i think i have both but when i open the .swf i don't know where to go to add an image to the existing images in order to make a newer .fla and uploaded on site instead of the old one.

I think it's a very basic work for experienced users like you guys so i hope some help as soon as possible and just let me know where i can upload the .swf and .fla files for you along with the image (s) i want to add.

Waiting some responses and thx in advance

You need to edit the .fla file - not the .swf file.

When you open the .fla file in flash, I imagine the images will be stored in the library (I think thats under window>library, or ctrl+L).

maybe make flash load external data?
