how to show node title when mouseover on image in the node by drupal views?
I don't think you can do that using views. However you can "hack" a way to add title element to a div, for instance.

go to your view config page

add a node: title field.

edit the node: title field.

tick "Exclude from display" and "strip HTML tags"

click save

move the title node to top of the fields.

edit your image field and tick "Rewrite the output of this field"

a textarea appears. write this code in the textarea

&lt;div title="[title]"&gt;[image]&lt;/span&gt;


Note: the [fields] are tokens. If you already have a title field, you don't need to exlude it, you can re-use it.

if the image displays another title its because the module automatically sets a title tag to the image. You can either change this tag with javascript:

document.getElementById("idElement").setAttribute("Title", "title");


or edit your image module and set the page title to be your title tag.
