This should take no more than 2-3 hours work I am looking to pay $20 per hour for a total of $60. The code is already written you will just have to modify it.

The details

On my app a user can upload a image, the only allow images are .jpg .jpeg .png. If a user attempted to upload a file named hello.php it would be rejected, if the extension was changed to hello.jpg.php it would accepted the user could have added some malicious php code to the meta of the image and it will now run.

The current upload code does a good job of blocking files other than images however it can be manipulated with image files by simply adding another extension after the .jpg and it will allow the upload a user can hide a php shell in the meta data and now run this code.
