Okay so why do Facebook apps ask for so much personal info?? Is it safe to use?

here is an app I really want to use on Facebook. What I'd like to know is if the apps on Facebook is safe? I doubt all are but most people use them so that's what makes me unsure. There is one in specific I want to use for my cover page since it has many nice covers I really like, from this site: http://www.firstcovers.com/

Yes, I know this is a basic question, but I'm somewhat new to the site and never used apps before. I personally don't like most of them and find them annoying that they are advertised on my page but I found one app that I'd really like to use. Thing is, it asks me for my profile info, email address, account info, and photos. I just don't get the last part really like why do they need my photos for?? Giving away all this info to an app on Facebook does worry me, but I noticed a lot of people used the app on this site (about 700,000 people do). Plus my friends use apps (different one though) all the time. And even recommend me to them though I usually don't bother. :/

Anyways is this safe? I'd like to know in general if the apps are safe or how can i know which ones are, like does it go by the info they request you? Plus specifically the one on that site I mentioned is what I'd really want to know most of all, if nothing.Yeah I know I'm a bit worried but I just want to be careful and make sure this info I give them won't be used/shared on other sites or anything bad. Thanks!

Be very careful. I avoid all apps. They ask this personal information for a reason - they plan to use it. That is what pays for the app they provide. You will never know if they're selling it or using it to advertise to you or both.
