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
(Heroku Postgres | Heroku Dev Center
) 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.
