I am a recent switcher and I have a few questions about iPhoto. I have a ton of pictures on my PC, and I have backed them up to a Western Digital Network attached drive, so both my Mac and PC can see them (and it's a nice backup of the PC). I have been going into iPhoto and selecting "import to library" to see my pictures in iPhoto. Under the Advanced tab, under Importing I have "copy items to the iPhoto Library" unchecked. I am curious, are my photo's on the network drive and iPhoto is just pointing to them or is there a separate copy on my iMac? If it is copying them, does that mean that if I get an external HD and use Time Machine, that it will make another copy there? If that's the case, I will have 4 copies of each photo. Also, under my wife's login I do not see any of the photo's I have in the library when I open iPhoto under her name. I do have Share My Photo's : Share entire library checked under my iPhoto. I was hoping she could see them without me having to do another step. Last question, sorry, but how do I navigate Finder to see these photo's? Using spotlight, it looks like I may indeed have photo's in iPhoto rather then my network HD. When I go to finder, I click on applications, then iPhoto. From there, I cannot drill any further, it just opens iPhoto. I want to see what folders are in there. I love the simplicity of OSX, but I feel like it is keeping needed information out of my hands. Thank you all for the help.
