guys I'm a total noob to macs and got my macbook pro yesterday but then idownloaded some stuff like transmission and thn when I restarted or shut down it will disappear later....and I accidentally uploaded photos from my phone twice means that there are 2 of the same photos inside my photo folder and it's hell trying to delete'em it's all mixed up....I can't seem to find a way to arrange my files in alphabetical order....help!

Guys pls help me can anybody tell me why when I upload pics from my phone sumtimes the pics would be duplicated twice? and I can't seem to arrange pics in my "All Images".....just wanna ask is "All Images" the equivalent of "My Pictures" on Windows? and when I delete photos from iPhoto it still remains in "All Images"?
