Hi Vibhijain, and thank you for leaving feedback. To prevent vandalism, Wikipedia does not allow new users to upload images until their account is autoconfimed - this happens after four days and ten edits. There are, nevertheless, three ways you can upload your image.
- You can make a request at this page to get your account confirmed early.
- If the image is free from copyright or released under a CC-BY-SA license, you can upload it to Wikimedia Commons, a site for free images from which Wikipedia can draw content.
- You can wait a few days and do a bit of editing, thus getting upload permissions automatically.
I hope this helps; if you have any questions please feel free to drop me a line or ask at the helpdesk.
