bbridle:

Well, I uncommented and changed one of the main lines and put another in place due to issues with https since our site runs on SSL:

 
url=(ssl?"https://":"http://")+String(Request.ServerVariables("HTTP_HOST"))+url;

url="https://"+String(Request.ServerVariables("HTTP_HOST"))+url;

Now I'm able to add a category whereas I couldn't before.  However, whilst I'm able to upload images and get the message "x file(s) have been uploaded!", I get the immediate error "System error: -2146697191." in a dialog box.  Refreshing the page gives:

"msxml3.dll error '800c0019'

System error: -2146697191."

/aspgallery/include_aspgallery.asp, line 58 which is "xh.send("");"

I've got the most recent versions of MSXML installed.
