Hello everybody! I am very sad, all my pictures from iphoto are gone I think I touch something I shouldn't but there is any program that i can recover them? something? they were more than 10k. :/

Restore from your back up.

Other than that, try tell us exactly what you did?

With the amount of information you've provided it's impossible to offer a solution. We can't see your computer so we need to know the details of your problem and setup, i.e:

• what system are you running?
• what version of iPhoto are you running?
• where is your library located?
• did you apply any updates or upgrades just prior to the problem occurring?
• are you running a "managed" or "referenced" library?

• what type of Mac?
• how much free space on your boot drive?
• what fixes have you tried?
