Re: image on Welcome to Page is it bad for seo
 

for some reason the variable {$ImagesDir} is not being parsed. Need to check the config and make sure that this is the correct variable.

This is what helpdesk answer:

2 I've inspected your cart and found out that you added the following code to the value of the 'txt_welcome' language variable:

<img height="480" src="{$ImagesDir}/pilot.jpg" width="640" />

Smarty tags (i.e. "{$ImagesDir}") cannot be used in the values of the language variables.
I replaced the code with this:

<img src="skin1/images/pilot.jpg" width="640" height="480" />

and that solved the issue.
