Once you upload your picture/gif/banner to a hosting site - like you did with myspace-shack, in the signature section, type [IMG = "your url here " ] (without the spaces). So in your case it would be [IMG = " http://server.myspace-shack.com/d21/lako2hhh.gif " ] (without the spaces), and after that type [ / IMG ]. (again without the spaces)
Side note though, I tried posting your myspace-shack url in my address bar to see the image and it said '404 not found'. So if the sig still doesn't work for you after the above method, I suggest just uploading the picture to tinypic.com. As a bonus, that site will also give you ready made html tags, so you can just copy paste the code they provide under 'IMG Code for forums and message boards' into your signature box.
Hope this helps. Also, next time you can just post such queries in the help desk section on the first page under 'Balika Vadhu Forum Important Topics'. You must not have seen it, but now you know! 😊
