"Μηδέν άγαν" (nothing in excess)
There are simple ways to extract pictures from your phone, for example via BlueTooth or sending it as an email attachment from your phone (over a wifi connection). These methods are ok for 1-2 pictures but not when you need to get all the pictures out. But thanks to the extensibility of windows shell, most phones and cameras appear as a virtual device under My Computer (or This PC if you prefer). You can drill down and find where the pictures are stored in the phone using the familiar folder concept, just like as if your phone was an external hard disk. You may find that your other file manager cannot enter such extended folders, but xplorer² can do it for you. All this without installing the phone's software; just connect the phone with its cable to a USB port.
Some phones (e.g my Sony W995) have a special mode to turn them into a proper USB stick, with drive letter and all. I am not sure if it works with an iPhone or you are stuck using its iTunes software.
Once you enter the phone and you browse its folders, you can see all the usual details like names and size/date information for your pictures, even thumbnail previews. The pictures are stored usually under a folder called DCIM, either in the phone itself or its external memory card.
The pictures are numbered consecutively like DSC02510.JPG or using the date as you can see in the pic to the right. Sorting by name puts the pictures in the order they were taken (equivalent to arranging by date). Using xplorer² in dual pane mode you can put the phone to one side and the PC folder on the other (e.g. a folder under My Pictures), then you can drag-drop the pictures to extract them off the phone.
Once extracted you can delete the media files from your phone, as in any regular folder (select and hit <DEL> key), making room for new photos. You can manually organize the photos once in your PC in folders, changing names, adding tags and all the other usual file management tasks.
