i usising file\_column to upload images in my scaffold.  
i setting quality compression images to value 70 for creating various  
versions optimized of uploaded image:

example of my code:

file\_column :image\_url, :magick =\> { :size =\> “600x450\>”, :versions =\> {  
“thumb” =\> “96x100\>”, “othumb” =\> “x80\>”, “vthumb” =\> “80x”, “big” =\>  
“600x450\>” }, :attributes =\> { :quality =\> 75 } }

but it not work very properly: if i upload images of 50 - 100 Kb the  
results thumbnail they weigh 3 or 4 Kb, that’s ok…  
but if i upload images of 500 Kb - 1 Mb my results thumbnails weigh is  
20- 30 Kb.  
Why?
