Hi guys, I was wondering if you are able to have a link\_to\_remote, having an image\_tag and the link\_to\_remote has a mouseover event that updates a div. Does the image\_tag need the mouseover event? I currently have: \<%= link\_to\_remote(image\_tag(@p\_image.public\_filename(:thumb)), :update =\> “big\_pic”, :onmouseover =\> {:action =\> :color\_change, :id =\> @p\_image.id})%\> I get this error on loading my page: You have a nil object when you didn’t expect it! You might have expected an instance of ActiveRecord::Base. The error occurred while evaluating nil.[] I also have this in attempts to solve my problem : \<%=image\_tag @p\_image.public\_filename(:thumb), :mouseover=\> remote\_function(:update =\> “big\_pic”, :url =\> {:action =\> :color\_change, :id =\> @p\_image.id})%\> The page loads but I get an error using firefox, missing ; before statement. Here is the html that is generated: ![Yellow_thumb](https://www.ruby-forum.com/system/0000/0022/yellow_thumb.gif?1211334531) I just want to have an image that fires a mouseover event that updates a larger image. Is there a better way? I hope someone can help me this.

You could try something like: ```
<%= link_to(image_tag("/images/ ``` get\_started\_normal.png", :mouseover =\> ‘/images/ get\_started\_hover.png’), { :controller =\> ‘user’, :action =\> ‘register’ }) %\>
