change file image storage to memory on-the-fly

does this make it so that this plug-in will work on Heroku's read-only file system?

[mrbrdo]

It doesn't use any files (at least not for generating the image), so it might work yes.

I'm getting this on Heroku when I try to get the image to load: uninitialized constant SimpleCaptcha::ImageHelpers::Magick
(although oddly the same configuration works for me locally)

the hiccup is in lib/simple_captcha/image.rb line 88, it is trying to call Magick

any ideas where Magick comes from?

I tried adding gem 'rmagick' to my application (Rails 3.0.9) gem file but that didn't quite work.

[mrbrdo]

yeah you need rmagick... try adding to your Gemfile gem 'rmagick', :require => 'rmagick' and then bundle install

[jasonfb]

yea I had the syntax wrong in my gem file, I found this and it seemed to fix that problem

gem "rmagick", "2.12.0", :require => 'RMagick'
