Ads pic name format and pic delete?.

A user can edit the ad and once if  a user uploaded the ad photo then it shows name of the pic something in this format 2_1264372036_1.png over the ad photo on the page to other user.

The name of the Photo should be same as it is saved in the user's computer?

Also once the pic uploaded then user can't delete it?
