PHP Web Spider/Crawler

Good day, unfortunately I do not speak English well. I would like a quote for your help.. I have to customize a Crawler GNU / GPL done in PHP ([login to view URL]) I wish that when you pass the mouse over the URL of the indexed page is opened in a level the image "screenshot" of the web page. The files containing the screenshot will be saved on the server. The name of the files "screenshort" to be added and associated with the web page within MySQL. Within the control panel Sphider the user can enter the URLs should not be indexed (URLs must not include). I would like to close the URL close to the results of pages that have been indexed appeared a button that allows you to automatically insert the relevant page in the filter "URLs must not include". In addition to the texts that Sphider indexes already successfully, it should also be added to the indexing of images. The files of the image will remain on the host of origin while in MySQL must be added the name of the files, the weight of the files, the size and the content of dell'ttributo description. Of course associated images (file name) must be stored together with the record of the indexed page. When a page should be re-indexed the images should be updated.
