how to check if a string exists ext

[Kevisazombie]

I have a function that loads jpgs into a bunch of movie clips as thumbnails. Some of the sections of my site have more buttons than i do items to thumbnail and I want them to dissapear if there is no corresponding thumbnail to its number.

loading the pics
pics/Web Design4.jpg
pics/Web Design3.jpg
pics/Web Design2.jpg
pics/Web Design1.jpg
Error opening URL "file:///C|/Documents%20and%20Settings/Zet
tler/Desktop/Kevs%20Graphics%20folder/Flas
h%20sites/portfolio%20site/pics/Web Design1.jpg"

right now the output just gives me that error and the button still stays there
I tried putting an if(path == "") in to check against it but that didnt work
so i need some how to check if a string exists external as a path.

can't you convert it to a string, and use indexOf(); ?

[Kevisazombie]

wait, what!? the location is in a compound string and i dont know how indexof would help me find if the external file exists

mmm indexOf is for checking of a entry exists in a array...

i suggest PHP with arrays, file_exists(), loops, and variable parsing for your flash.

I actually just made one of those today. I made an html version, and a flash version. Loads resized images - or thumbnails - into duplicated movieclips and shows the full image on click. A half decent application.
