115588 fix upload bug

Hello, I have a My_eGallery module into phpnuke. This is serveral months ago changed so I don't need to approve pictures anymore, but they're activated right away. There are some bugs in it: - Long filenames are not good For example when someone uploads: [login to view URL] the script only takes [login to view URL] - Dots in filenames are not good For example: [login to view URL] will be after upload [login to view URL] This problem can be fixed it script makes unique names - Image must be thumbnailed with image magick
