Question

Is there any way to change the provide an image for the button in the following code

<%= button_to 'Edit treatment', edit_treatment_path(@treatment), :type => "submit", :class => "style3", :method => "get" %>

Answer 1

If you are trying to submit a form by image click (assuming that since your type is "submit") you can use

image_submit_tag("your_image.png", :class => "style3")

If you meant a standard button you can use

link_to image_tag("your_image.png"), edit_treatment_path(@treatment), :class => "style3"
