i copied the code and using dreamweaver saved it as a php file and then copied it to the root/plugins folder but its not showing up.

Sorry, don't have a clue

Maybe you should put the plugin on our unsupported repository (folder of the same name with the file itself)? Or even your own?

Could be a simple copy&paste issue, often "kills" chars like quotes, especially in JS code.

This time i typed the code myself completely without any general mistakes but still it isnt showing up. So i decided to try the traditional method. Changed the css of admin and then Voila! But the upload isnt working for the user. It states that No album is selected. Any tips about it??

Just made a plugin available on GitHub.
You can replace the default logo with your own.

Hope it works this time ;-)
