Adding Zip uploading feature to an image host

Hello I have an image host ([login to view URL]) and it's coded in PHP. I have another image host, hosted on the same server, called ([login to view URL]). Pixdaddy has ZIP file upload feature but Picmecca doesn't. I need you to COPY the code that Pixdaddy uses (also PHP) to allow ZIP file uploads (I need the COMMON UPLOAD feature from Pixdaddy, only) on Picmecca, in order to allow ZIP uploads for Picmecca, as well. The ZIP upload feature shall allow the user to select a picture category, from Picmecca's category tree, at the time of uploading, so that pictures are saved under the appropriate category selected by the user. ZIP uploading feature shall be placed on the same window as the single image upload feature, so visitors can see it easily. The max Zip file size shall be the same as on Pixdaddy. In conclusion, the job is to make Zip file uploads possible for [login to view URL], using [login to view URL] image hosting script's existing PHP code for the COMMON UPLOAD feature. I JUST care about Zip uploads taking place, so forget Pixdaddy's family safe-not family safe-resize image- make the images private?, and watermark Buttons. IMPORTANT: In case you think it's easier to use your own code, instead of copying it, I'm open to any suggestion you may have. Main thing is to achieve the best result, the fastest possible.
