Small image scraper with PHP

For a job at the university I have to create a small system to generate images (search google) cut in exact sizes with changes in brightness and contrast and name change of the files for download. I attach images The textarea field each line break is a Google results query. On the right side it has default options and that can be changed according to the user's needs Finally, we have the option to download individually or all at once. The update button is to change the image to the next one if the user does not like the first result thrown. The first option thrown that is the image 11 (attached capture) and if the user disagrees with the result, when you click on update generate another image (usually from the next search result). The system is very simple, everything must be done in PHP and its libraries, the person selected is that you can do it faster
