error while embedding images & no pretty_face report when put as default profile

[shekss]

hi ,

i have the below code in my env.rb to generate screenshots for failed and passed scenarios.

def take_screenshot(scenario)
if scenario.failed?
scenario_name = scenario.name.gsub /[^\w-]/, ' '
time = Time.now.strftime("%Y-%m-%d %H%M")
Dir.mkdir("failed_png") unless File.directory?("failed_png")
filename = time + ' - ' + scenario_name + '.png'
screenshot_path = './failed_png/' + filename
save_screenshot(screenshot_path)
embed ('../../failed_png/' + filename), 'image/png'
else
scenario_name = scenario.name.gsub /[^\w-]/, ' '
time = Time.now.strftime("%Y-%m-%d %H%M")
Dir.mkdir("success_png") unless File.directory?("success_png")
filename = time + ' - ' + scenario_name + '.png'
screenshot_path = './success_png/' + filename
save_screenshot(screenshot_path)
embed ('../../success_png/' + filename), 'image/png'
end
end
After do |scenario|
take_screenshot(scenario)
end

the above code creates images in my success_png folder . here below the snap shot of my folder structure .

when i do this , i get the pretty face report of my scenario, image is displayed correctly but i get the failure scenario due to the error in the command line like below:

and when i inspect the image in pretty face report html, i can see the path is valid and i can see the image when i click , but why this error? here is the src in the pretty_face html report

src="images/../../success_png/2014-05-13 0949 - Valid Login.png"

due to this my scenarios are failing. can u let me know what i shall do to get rid of the this error . i am using pretty_face version 0.10.1 with actionpack 4.0.4.

another issue , i am facing is , no matter what if i put the pretty_face arguments like this in default yml file in cucumber, it doesnt run the report. i have to always put a seperate profile in the yml for generating pretty_face report. i am doing something wrong ?

default: --format pretty --tag ~@wip --format PrettyFace::Formatter::Html --out results/index.html
