image upload vs file upload?

i have seperate directories for browsing images and documents, i want to keep them seperate.

I edited the files that i could find:
config.js
upload.asp

created fileupload.asp which is reflected in config.js however as much as I've tried I can't for the life of me figure out why its uploading everything to the images directory anyway.

the reason for the separation is that the files are listed using filesystemobject and i don't feel to write a lot of redundant code to parse out the images, when i can just as easily have two folders.

there are no issues with permissions and the uploads do occur. I just can't find anywhere in the code where i can declare specifically the folder for upload, besides the sDirUrl = "/docs/" in the newly created fileupload.asp

the sDirUrl = "/images/" is the correct path for the upload.asp page, its of no issue.

is there something perhaps in the class_upload.asp that i'm unfamiliar with that may be redirecting the uploads to the images folder? or is it in the dialog window itself?

I haven't been able to find it
