Show image after changing format in Rails using imagemagic

I want to show images, I've got urls to do that, but I've got one problem - all of them have extensions 'ico' and I want them to be converted to 'png' and then shown in the view. Is there any simple way to do that or I have to format and save them into model and then show?

You can do it on the 'fly'. There are couple of gems which can help you.

Please read these articles first, it may help you for good start:

https://www.sitepoint.com/image-processing-rails/

https://www.new-bamboo.co.uk/blog/2010/01/13/dragonfly/

http://www.learnwithdaniel.com/2015/09/dragonfly-rails-models-with-images-and-files/

Dragonfly gem: https://github.com/markevans/dragonfly

The Dragonfly gem generates new versions on the fly, that can be very resource consuming, so think about using server cache solution. ( rack-cache gem )

In case that you are using carrierwave gem:

Hope it helps
