hi, very new imac owner after gateway for many years. so im slowly learning my way through it all. not sure if this is the right place to post this question, but on our imac we have 4 different users, me, wife, and kids, we all have our own accounts. i downloaded some of my pics off my camera, but im the only one who can view them? i did go in the tab on iphoto and clicked shared also. is there a way that we can all see the photos? also, how do i attach a photo to a online forum/ or webpage?
