wordpress developer - photo accessing with custom authentication

Description: I need a plugin for wordpress that will provide access to photos within subfolders on my server after a successful custom authentication. details below Situation: Event photographer takes photos of people, then saves the photos in individual folders. each folder is named by the ID number of the person photographed (example: folder named 123456789 contains the photo/s of a person who's ID is: 123456789). these folders are then uploaded by ftp to a webserver running a wordpress installation. Required: people who attended the event whould be able to access their individual photos (not an open gallery with all of the photos). the process goes like that: 1. the home page of that website will have two input fields: ID (numeric, 9 digits) and DATE (ddmmyy - 6 digits with no slashes). below these two input fields is a submit button. 2. when submit is pressed, the plugin checks if a folder named by the ID number exists, and that DATE matches the date the photo was taken (using EXIF "date taken" data). if there's a match, a page with the photo/s within that folder will be loaded with a download button below the photo. If authentication failed (either no such ID and/or no date match) an error message will be shown, stating the false field: no such ID / Date mismatch. 3. plugin backend will be in English, however frontend whould be translatable (I will create translation) so plugin should be ready for language file. Note: I will translate to Hebrew, a RTL language 4. backend features: * select photos folder (the folder in which all the subfolders are contained) * option for false login timeout (after X false attempts block that IP from login for Y seconds) * option for captcha * option for automatic background delete of old folders that are X days old (if turned on, plugin will execute that delete once a day in 01:00) * statistics (count successful logins, failed logins, photo downloads) * log 5. I need to be able to design the pages in the wordpress editor by myself, including blocks, graphics, text etc... 6. Cross platform is a must: Desktop, Mobile, Tablet... 7. plugin will be delivered as an installation package (zip file) that I can independantly install using wordpress backend
