I used pure php upload to create an upload page. It can however only upload the following image extensions. gif|jpg|png|bmp|jpeg
I looked in the Script library and found this code in the javascript file
re=new RegExp(".(gif|jpg|png|bmp|jpeg)$","i");
I am sure this is the code I need to modify to allow pdf files to be uploaded. For Javascript experts, the entire code is as follows. Please help will be appreciated

To allow pdf files you will only have to add pdf in regex using alteration.
Regex: re=new RegExp("\.(gif|jpg|png|bmp|jpeg|pdf)$","i");
