that would need to be

> \<%= image\_tag(‘e.image’, {:id =\> e.id, :onload =\> “gan()”}) %\>

You would need to include the relevant javacript file using  
javascript\_include\_tag

It may be one of the following two reasons for getting the problem.

1. You have not included the relevant javascript in the rhtml file.  
The following statement should be there in the rhtml file.  
\<%= javascript\_include\_tag ‘ganesh.js’ %\>

2. You have not called the javascript method inside quotes.  
Try with,  
\<%= image\_tag(‘e.image’, {:id =\> e.id, :onload =\> “gan();”}) %\>
