I am trying to do something similar to the above question. I am trying to make users post and upload images from front-end. I have already done the post form and its working.

I just followed and tried the answer posted by Robin I Knight [upload-post-thumbnail-from-the-front-end](https://wordpress.stackexchange.com/questions/11395/upload-post-thumbnail-from-the-front-end). Sadly i couldn't get it to work. Is there anything i'm suppose to change or edit?

Thank you.
