You question is still not clear. Are you a devloper ? I have created a wordpress theme myself. Some themes have the inbuild option to change the logo image from gallery. If you are looking for a plugin to change the logo of your current theme, you can put a link of your website and I can tell you how to change the logo. But if you are a devloper and creating a plugin for other people and planning to upload it to wordpress codex, why are you showing the plugin code of some other author(that doesn't make sense to me)? Please explain what you are tying to do. And if you have written your own code for plugin show me that one. or else just paste the link to your website.

 

Actually I am studying and we got a project to build a Plugin, the topic is on particular date my website logo should get change for example valentine day feb 14 the logo of the image should change according to that event . But my doubt is I want a option to select image from media Library and date also for Logo and Display that Logo on particular Day....

 

hmm.. I get it. But have you written some code for it. Because you see nobody is going to write the whole plugin for you(because if they wanted to, they would released the plugin under their name). People can only help you fix the errors in code of the plugin that you would might have. I would suggest that you should read this http://codex.wordpress.org/Writing_a_Plugin and if you have any questons you should ask that on wordpress support. http://wordpress.org/support/
