สอบถามปัญหาเรื่องการลิงค์ดูรูปภาพ มันพอคลิกแล้วมันไม่ยอมลิงค์ไปดูรูปถัดไป

<Form method=post action="insert.php"
enctype="multipart/form-data">
<table>
	<TR>
		<TD> <div align="right"> รูปภาพ : </div></TD>
		<TD> <Input name="photo" type="file" id="photo">
	</TR>
	<TR>
		<TD valign="top"> <div align= "right"> คำอธิบายรูปภาพ : 
		</div></TD>
		<TD><textarea name="detail" cols="35" rows="4" id="detail">
		</textarea> </TD>
	</TR>
		<TD>&nbsp;  </TD>
		<TD> <input name="submit" type="submit" value= "submit">
		         <input name= "reset" type = "reset"  value= "reset">
	</TD>
	</TR>
  </Table>
	</form>

while ($r=mysql_fetch_array($result)) {
