Phoca Gallery customisation

Hello, I need some costumisation on the phoca gallery extension. If not possible with phoca I accept other software with similar functionalities working with all browsers. Currently we have implemented iphoca n a website, accessible to a link in the main menu (photo). I would like the following modifications: 1) when clicking on the menu "photo", the users should see an automatic slideshow of the last category of photos added. This also whenever the slideshow is opened 2) there should be the possibility to change the category of photos (eg a menu on the left) even when the lightbox is opened. 3) today I've some issues with Safari, Chrome and Firefox browsers: when I close the JAK lightbox of phoca gallery all the links in the page do not work (photos, menu etc) and I've to reload the page. With IE everything works correctly. 4) by opening the slideshow lightbox a script to avoid the copy of the picture should be active For the backend: a) easier possibility to choose the category before doing the multiple upload and not after. This is because when the upload is done we will upload many images and it will not be easier to remember the last photo uploaded. Thanks
