watermark problem with flexible-upload plugin

I was uploading the watermakr file in the wrong format in my ftp program.. oops

I’ve tried this plugin it’s works great but got some problem i cannot resolve it..

The problem is in watermark part:
When I patch animated gif the output will be a still image or not animated, why this occurs…
How can i overcome this problem, is it got any other subplugin to resolve this problems..

Please anyone help me…
