is there anyway to make pictures or words appear on an already made swf file on myspace?

Don't think so. They have to be added in to the flash file before they are prepared for the web as a swf file.

Edit: Oh, this is if you meant pictures and words included in the flash animation. I think you would be able to put them on top of the flash animation using a div and different z-indices but I don't know if this actually works. =\

oh then i was wondering if there was any other programs to make flash in my trial for macromedia flash has expired /:

I know that there is another popular program out there called SWiSH. However, if you are going to use the Adobe Flash .fla file in SWiSH, it won't be compatible. =\

oh well i converted the adobe to swf so it works (: anyways do you know how to put links onto the file?

You can't add links once you've exported it as a .swf. =\ You can only do that in the original .fla file by creating buttons. But it all boils down to what you want to do and how simple or stylish you would like the navigation to be.
