Parameters are getting lost when you use redirect or redirectAction result type. To retain request parameters you should use dispatcher result type. This is default result type, and it will be used if you miss type attribute of the <result tag, like this:

<result>/ThankYou.jsp</result>

Why <s:param> tag giving null value. Because the value is converted by OGNL to integer value before adding it to the URL and it throws NumberFormatException because no such integer can exist. The value exceeds the maximum in Java for integer value. You should use string value in <s:param> tag, like this:

<s:url var="remoteurl" action='userimageGrid' escapeAmp="false"> 
    <s:param name="imeino" value="'66666666666'"/>
</s:url> 
<s:a href="%{#remoteurl}">Call</s:a>
