PHP streams are not always binary safe by default, at least on windows (linux has no 'b' but for API compatibility reasons afair). Unless you specify the binary mode explicitly. A common problem is to run under cgi, cli or apache on windows, the default mode may differ (apache for example is/was not binary safe) Cheers, -- Pierre http://blog.thepimp.net | http://www.libgd.org
