Online screenshot script

I need a php script with GUI that can have a url entered in to it and a choice of timescale (daily, weekly, monthly) and then depending on the setting the script needs to take a screenshot of the specified URL, save it and allow it to be viewed in a structured way. ## Deliverables I need a php script with GUI that can have a url entered in to it and a choice of timescale (daily, weekly, monthly) and then depending on the setting the script needs to take a screenshot of the specified URL, save it and allow it to be viewed in a structured way. The image must be a jpg and optimised to around 250k in size per image. The system needs to have a signup form, login, account verification, security, validation on fields, security against code injection on fields etc So the end vision is this... I have a system that a user can login and set a url to be screenshotted at chosen intervals - then they can view old screenshots (must be dated and displayed in date order) I also newed an admin level to allow users more URL's to screenshot and also control how many screenshots are saved by default for each user. It will need to move 'old' screenshots to a new folder on the server for manual deletion. The user level must be able to handle the choice between different URL's as well. I don't need a payment system integrating. Each user would need to be able to start/stop screenshots for the URL and also delete the screenshots they don't want. Admin would have a total of screenshots for each user. User would have a total of screenshots they have. Users would have a screenshot limit and admin could extend this per URL. ## Platform LAMPS
