You have already got a better approach from PeterPeiGuo but if you are curious about what's wrong in your code, here are a few things which I noticed
- You are not comparing the names, rather you are comparing the existence of names in db and in the array.if(($row->{image_name_1} ne "") eq ($pics[0] ne "")) will increment $flag_pic even if $row->{image_name_1} is "xyz" and $pics[0] is "abc"
- (Let us assume previous error is corrected) You are assuming the order to be same in db and in array. If name in first row of db matches with that of second element in the array, it will go unnoticed and you will fire an "insert" query.
You definitely need to modify the approach

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
