Implemented some fileds to make it easier to access gallery and a new field for a Successmessage when an image succeedes in uploading
The successmessage is now working. You can remove it if you want to. It wont stay up there if you go to another image, but that shouldn't be much of a problem
Inserted a fieldset and a legend for it to look a little better.
space
Added the scrolling to the page. Was hard to understnad, but then I found out you had to do it on the overflowed element, which I didn't do at first. Now it scroll to the image when you click on it, or really, it load another page and the scrolls to that image
Changed from a scroll left to a animate scrollLeft, this way it looks a bit fancier, but it doesn't really change anything other than that
Adding some comments and removing some unused code
