multiply file upload with thumbnails

[rcouser]

I have been pulling my hair out all day trying to get this working. Could some kindly please help.

 

<form name="update" id="update" method="post" enctype="multipart/form-data" action="">
<p><label for="image">Image 1 (W:532px - H:399px)</label>
<input type="hidden" name="MAX_FILE_SIZE" value="<?php echo MAX_FILE_SIZE; ?>" />
<input type="file" name="image[]" class="sampleimage" /></p>
<p><label for="image">Image 2 (W:532px - H:399px)</label>
<input type="file" name="image[]" class="sampleimage" /></p>
<p><label for="image">Image 3 (W:532px - H:399px)</label>
<input type="file" name="image[]" class="sampleimage" /></p>
<p><label for="image">Image 4 (W:532px - H:399px)</label>
<input type="file" name="image[]" class="sampleimage" /></p>
<p><label for="image">Image 5 (W:532px - H:399px)</label>
<input type="file" name="image[]" class="sampleimage" /></p>
<p><label for="webstatus">Show On Web</label></p>
<p><input type="submit" name="save" id="save" value="Upload" /></p>
</form>

Any help would be much appreciated
