Hmmm... maybe a IE-Problem...
Add this:
header("Content-Disposition: inline; filename=$file");
header("Content-Description: PHP Generated Data");
Having the same problem with .jpg...
In Netscape you can do a right-click an select "save image as..."
without any problems... IE always prompts for "unnamed.bmp"
In the Articles-Section i found out, that's a problem of the IE, only... :rolleyes:
