How to replace image form folder by another (NEW) image uploaded by user?

[ilya Kraft]

Hello,

Alright, so I came across the following problem. I have system where users can upload their profile images. Images get stored in folders with member id's. The issue is: When user uploads image it get's set as their profile image, but when they upload new image it get's stored in the folder with old image, so now they have 2 profile images. And this causes trouble. I need to automatically delete old image when user uploads new image, so replace old to new.
I will provide scripts that I use for upload now, So if you have any ideas on how to fix this problem I would really appreciate it, Thank You )))

    <input type="submit" value="Upload It"/>
