What are you saying ? You say this Script isn't secure ? You use it on your NovaHQ site. Why wouldnt it be secure if you use it yourself ? Or did you only secure it properly afterwards for your own site only ?
If its not secure really, you might add that to the description in your scripts downloads so people know. You cant expect anyone that uses a script for something like that, to be an expert in PHP. Thats not the point.
No offence intended btw.
Besides, there isnt really a good script i know of, thats designed to be for maps. Using a general download script was not what I had in mind. THats the good thing about your script, it is only ment for that.
