It is no good saying that you got another error without telling us what that error is.  Also tell use what operating system you are using.

What do you mean when you say "when i use it in gemfile gem install rmagick".  Exactly what have you put in Gemfile?  Exactly what are you doing to get the error and exactly what is the error?

Your Heroku app has a separate database. Check out `heroku pg:push` and `heroku pg:pull`  (https://devcenter.heroku.com/articles/heroku-postgresql#pg-push-and-pg-pull ) to learn about how to move data between your local database and the Heroku one.

This sounds like you're saving uploaded images to the Heroku filesystem. This is NOT guaranteed to be preserved when your dyno sleeps. You'll want to look into using something external like S3 to store files.
