Purging images

[odisey]

I have some snippets of ideas from Google - I am not sure how to do this.  I am sure it is probably easy. 

 

Here is the layout idea: A realestate company site.  There are five pages - each a different area.  For example page 1 is HOMES, page 2 is LAKE PROPERTY, and etc....  On each page I want to:

 

1) associate a thumb_nail with a description of the property.

2) forward to a new page with multiple images if the thumb is clicked

3) when updating the site I want to purge all images associated with a listing when the listing is deleted from the db. 

 

 

I am thinking the images are uploaded to a images_folder probably with a unique name generated on upload; perhaps a time-stamp.  I am not sure how to accomplish this yet - any ideas are greatly welcome. 

 

Thank you,

Marc
