unable to store image in remote location

[gpat]

Hi everybody ,
i am new imageMagicK. I started well but currently i am stucked into something. i am trying to resize an image . Here is command
convert -resize 400X300 http://mydomain/images/old.jpg http://mydomain/images/new.jpg
i am getting errro message no encode delegate for this image format
but if i replace above command with this one its works
convert -resize 400X300 http://mydomain/images/old.jpg d:/images/new.jpg.

Its means that i am able to store image in local machine and not in remote machine. Is it possible to store image in remote location . Initially i thought i need to install delegate. but i am running imageMagic on windows server and i have selected all the options. how to i check if all the delegate are installed . i search jpeg delegate for windows on net but no luck

Here is configuration

Version : 6.3.6
ImageMagicK installed on : Windows
Storing image on Unix ;

Please help me .

ImageMagick can read remote images but cannot write them.
