Please do not panic !!! As per FAQ UPSEE 2016
Candidate has been given the opportunity to review the form and correct information including photograph as many times as he want before finally submitting it. Once application is finally submitted, it cannot be changed.
Although, the candidates will get a chance to modify some selected entries of the Application Form between March 28 to March 30, 2016
I am not very much sure about the 'Image Correction' will be available or not at the later stage. So I would suggest you that please contact official for the same.
