I suspect that's not exactly what you want. Given that you probably don't know how big the image is, and can't be sure that there isn't an EOL character in the binary data, and it's binary data and I'm not sure that fgets is binary safe, you probably should do something like } else { $output = fread($fp,999999); fclose($fp); to get the file. Less typing and binary safe :-) > } > $filename = > "/usr/home/inetwor6/www/vhosts/bocaratonchamber.com/graphics/weather/current > .gif"; > $fd = fopen("$filename", "w+"); > fwrite($fd, $fp); Here you are trying to write the file pointer from the 'get file' process to the file you've opened locally; you probably want to write the contents of $output, which theoretically contains your image. > > I've tried many combinations of the above and imagine one of you has done > this and has a snippet solution. > > Thanks in advance, > Dan All untested, but may get you going. -- David Robley | WEBMASTER & Mail List Admin RESEARCH CENTRE FOR INJURY STUDIES | http://www.nisu.flinders.edu.au/ AusEinet | http://auseinet.flinders.edu.au/ Flinders University, ADELAIDE, SOUTH AUSTRALIA
