For Rails 3.2 add this under config/initializers
module ActionView::Helpers::AssetTagHelper
def image_alt(src)
return ''
end
end
Pergunta
I rather have a blank alt attribute if an image is missing instead of the filename of the image (who ever wants this default behavior anyway?)
Is there a way to make a system configuration so image_tag sets a blank alt attr if no alt was given?
Just to be clear: I am not interested in image_tag('path/to/image', :alt => '') I am interested in setting it once for all the image_tags.

You can monkey-patch ActionView::Helper#image_alt
with:
def image_alt(src)
''
end
Or use your own version of image helper
#ApplicationHelper
def my_image_tag(source, options={})
options(:alt) = ''
image_tag(source, options)
end
Then use it, my_image_tag "test/test.png"
