I do not know anything about UBB code: does the "Image" button cause the image to be stored on the Bulletin Board's server? I thought that the image was on the webserver of the person who posted it and the UBB Image tag caused the image to be automatically displayed (taking up bandwidth but not server space). If I look at the addresses of pictures displayed in the Forums, they are not forum addresses, they appear to webservers of each poster/writer.

Is this a storage-space problem/concern or a bandwidth concern/problem?

I am not being argumentative, just trying to get a clearer idea about the workings of the various UBB Codes.

Thanks,
Tim
