Copying gif files

[Gerald E. Bennett]

Hi everyone,
Somehow when I copy gif files to my
classes dir before building the jar
all these files are mangled.

Is there something special that I need to do or how can I fix this problem ?

here is the code that I use:

<copy todir="${build.dest}" filtering="on">
        <fileset dir="${build.src}" includes="**/*.properties"/>
</copy>
<copy todir="${build.dest}" filtering="on">
        <fileset dir="${build.src}" includes="**/*.properties"/>
</copy>
<copy todir="${build.dest}/icons" filtering="on">
        <fileset dir="${build.src}/icons" includes="**/*.gif"/>
</copy>


Thanks everyone
