[D7] Graphical poll

There are some errors reported by automated review tools, did you already check them? See http://pareview.sh/pareview/httpgitdrupalorgsandboxwaspper2200805git

We are currently quite busy with all the project applications and we prefer projects with a review bonus. Please help reviewing and put yourself on the high priority list, then we will take a look at your project right away :-)

Also, you should get your friends, colleagues or other community members involved to review this application. Let them go through the review checklist and post a comment that sets this issue to "needs work" (they found some problems with the project) or "reviewed & tested by the community" (they found no major flaws).

Code review:

• Overall: add more comments in between code lines.
• Make sure to use the same indents (2 spaces) throughout the whole code (for example graphical_poll_form_poll_view_voting_alter in .module).
• Add @param and @return value information in the comment block above function graphical_poll_check_choice

1- You are assinging alt the link which is very bad option you may want to input it from user.
2-Some links are very large http://themerrymakersisters.com/wp-content/uploads/2013/01/VEN-virtual-e... . And form accepts only 128 lenght fields so the solution of 1 and 2 will be create your new textfield which would use states api, so either user has option to enter some poll text or image fieldset with alt. You can look for ajax_example and ajax_example node form alter to achieve this.
3- This function is looking useless to me pardon me, if it is wrong commenting it, your code also work without it

function graphical_poll_preprocess_poll_bar(&$variables) {
  if (graphical_poll_check_choice($variables['title'], variable_get('graphical_poll_validation_method', 'string_pattern'))) {
    $data = array(
      'url' => $variables['title'],
      'alt' => $variables['title'],
    );
    $variables['title'] = theme('graphical_poll__choice', array('data' => $data));
  }
}

What is the need of it?
