Image hosting Site

I have an image hosting site in need of a good update, it is a bit popular and I want to change the look and functionality. The following image hosting script MUST have the following items and must be performed in the sequence shown below. Requirements: - Admin panel to view uploads and registered users - Client registration (not required to upload images, optional). When client registers they can keep track of their uploaded images. - Ability to change allowable upload size and file type (in admin panel) - Creates thumbnail (100x100) and shows the dimension and size of the file that was uploaded (after upload of image has been done) - Supports up to 4 images being upload at one time. This option should be on a secondary page. Main page only has 1 upload. - Using cronjob any image over 30 days old that has been accessed less than "x" amount of time is removed automatically. The "x" being setup in admin panel and can be adjustable. Steps when visitor goes to site to upload image: [1] Seems upload image, browses local pc and uploads. [2] After upload is done, visitor sees the following in this order: - Thumbnail viewable, top - Thumbnail text link in box followed by other types of text links to image: [url=[login to view URL]][img=[login to view URL]][/url] and [url=[login to view URL]][img=[login to view URL]][/url] and HTML link to image and Direct link to image and A html link to site- Thanks to ImageDomain for [URL=[login to view URL]]Free Image Hosting[/URL] When anyone visits the image it is shown with our main website wrapped around the image. Again see other image hosting for example. Demo of script will need to be provided before escrow exchange is made.
