Hi Nitish,

If you are static resource for image in vf page then you have to use this syntax
{!$Resource.logo}. You have missed $ sign.

Thanks

Hello,

The problem is {!resource.logo} that is not resolved.

<apex:image value="{!resource.logo}" width="220" height="100"/>

You can try this at first:
<apex:image value="/img/logo.png" width="220" height="100" />

But you need to identify clearly what is this logo because there are many syntaxes for resolving the images:

Hi Nitish,

Try the below change in the <apex:Image> Tag:

I think you are missing $

<apex:image url="{!$Resource.logo}" width="220" height="100"/>

or

<apex:image i value="{!$Resource.logo}" width="220" height="100" />

If it helps don't forget to mark this as a best answer!!!
