Hey There!

I am a newbie with Adwords Editor. I managed to import all information to Adwords Editor via csv file except the images. I get an error “Failed to read image ad’s image data.”

I tried different ways to import it but get the same error:
(Header Name => Field)
image name => book.jpg (where does editor locate it?)
image file name => c:\book.jpg
image url => http://www.example.com/book.jpg

Any ideas?

Thanks!
