This project has three steps.
Capability to upload three images for a record into a MySql Database. Most likely be a blob column.
New upload script that has a confirmation from a link sent to their email address. All data is stored in a temporary table until confirmed from the link sent to email address, then it will be addedd to the permanent table. And the upload script must also have a delete script as well, that visitors can delete their record.
Add anonymous user id if a user wants to hide his email address. This will be an option while posting items. So for those users, we don't have to display actual email address in the form but the confirmation mail should go to their actual email address.
It is a quick project. Let me know if you have any further questions.
