Image locating

[mrtblt]

As i am developing the site offline on my computer, i dont have any problem with file locating.
To put images on the page first i check if the respective image exsits

		$sql = mysql_query("SELECT * FROM urunler order by kod") or die(mysql_error());
		if(mysql_num_rows($sql) == 0) { echo'<tr><td>Yazar bulunamadi!</td></tr>'; }
		else {
		while($urun = mysql_fetch_object($sql)) {
		$filename = '/images/products/'.$urun->kod.'.jpg';	
		echo '<div id="box">
			'.$urun->kod.'';
			if (file_exists($filename)) {
			echo '
			<p align = "center"><a href="/images/products/'.$urun->kod.'.jpg" rel="lightbox" title="'.$urun->tanim.'" width="100">
			<img src="images/products/'.$urun->kod.'.jpg" width="90" border="0" align="top"></a></p>'; }
			else {
			echo '
			<p align = "center"><a href="images/products/no_image.jpg" rel="lightbox" title="'.$urun->tanim.'" width="100">
			<img src="images/products/no_image.jpg" width="90" border="0" align="top"></a></p>'; }

I check the existence of the image if the image doesnt exist then i print the 'no_image.jpg' file.

Although i have images for most of the entries, for all the entries page prints 'no_image.jpg' file.

It means that it can access the directory ''images/products'. But
why i cant access and check existence of image with
$filename = '/images/products/'.$urun->kod.'.jpg';

As i told you it works offline fine on my computer.

my website is http://www.omega-intertrade.com/

You can also check it here.

At first I thought it was:

$filename = 'images/products/'.$urun->kod.'.jpg';

But I'm not sure. Give me 5minutes.

UPDATE:

As far as I can see from the code and the website the images you are trying to dectect if they exist are:

images/products/2610501.jpg
images/products/2610601.jpg
images/products/2610602.jpg

Attempting to find these on your site in the same folder as the no image (as implied by the code) results in no files being found:

http://www.omega-intertrade.com/imag...ts/2610501.jpg
http://www.omega-intertrade.com/imag...ts/2610601.jpg
http://www.omega-intertrade.com/imag...ts/2610602.jpg

Either the files aren't there or you are creating the wrong file name/path in the code.

Thanks for your attention. I found the solution.

The extensions of the images which i uploaded was capital letters like '.JPG'

This was the problem. My code was checking 2610501.jpg and found nothing because the image i was looking for was saved as 2610501.JPG with an extension formed by capital letters.

But i have another question :

my site doesnt seem to be Valid XHTML 1.0 Transitional. Where it fails to be valid. What should i do to make it valid?

Ahhh yes. That's happened to me before.

These days I always sanitise all my data and files. For example make all file paths, file names, file extensions lower case.

Its always better to use one method across the whole site.
