Sometimes I receive a flash banner to use with clicktag.

I know that the URL can be passed with a variable (param in object tag or flashvars in embed tag).

But I also know it is possible to use a txt file that has the text with the URL:

The problem is that I generally have my banners in folders (for example /banners/country/banner1.swf) and I don't know where to upload the txt file (sometimes it works when I upload in the root folder sometimes it doesn't).

The second problem is, suppose I have more than one banner, how do each banner knows which txt to use?

Many thanks!
