<p>I am selecting all  tags where href attribute is starting with "picThumbImgA_" as below.</p>

<p><code>$('a[id^="picThumbImgA_"])')</code></p>

<p>now i want to update some attributes of first four  tag. I can select first as </p>

<p><code>$('a[id^="picThumbImgA_"]):first')</code></p>

<p>and last as <code>$('a[id^="picThumbImgA_"]):last')</code> 
odd as <code>$('a[id^="picThumbImgA_"]):odd')</code>
and even as <code>$('a[id^="picThumbImgA_"]):even')</code></p>
