What's this?

image_alt(src) public

Returns a string suitable for an html image tag alt attribute. The src argument is meant to be an image file path. The method removes the basename of the file path and the digest, if any. It also removes hyphens and underscores from file names and replaces them with spaces, returning a space-separated, titleized string.

Examples

image_tag('rails.png')
# => <img alt="Rails" src="/assets/rails.png" />

image_tag('hyphenated-file-name.png')
# => <img alt="Hyphenated file name" src="/assets/hyphenated-file-name.png" />

image_tag('underscored_file_name.png')
# => <img alt="Underscored file name" src="/assets/underscored_file_name.png" />
