unzip/untar the netpbm file, you should have a folder titled 'netpbm'
upload it to your webserver, and if you're using WS-FTP Pro, then right-click on the netpbm folder -> goto Properties
you will see Read,Write,Execute check boxes, and right above them, a Numeric Value box
change the numeric value to '755', then click OK
do the same for each of the netpbm files INSIDE the folder, *except* for the Readme file.
what this does, is make all the files executable from your server account
if you use a different ftp program, then just right-click on the files and explore your options, looking for anything that allows you to change the Read, Write, Explore options, or to change the 'chmod' value
