[Rodrigo Souto]

Rodrigo Souto started a new discussion on app/views/shared/_change_image.html.erb:

> +<%= file_field_tag("#{for_attr}[uploaded_data]", { :onchange => 'updateImg(this.value)', :id => "pictureInput" } ) %>
>  <%= labelled_form_field(_("Image Label:"), text_field_tag("#{for_attr}[label]")) %>
>  <%= button_to_function(:cancel,_('Cancel'),"jQuery('#change-image-link').show(); jQuery('#change-image').hide()", :id => 'cancel-change-image-link', :style => 'display: none')%>
> +
> +<script type="text/javascript">
> +//<![CDATA[
> +    $(function() {
> +        $('#pictureInput').on('change', function(event) {

> +          var reader = new FileReader();
