header / header.php top logo problem

[the_error_king]

I am having issues with the top logo.

I was able to edit it find in includes/header.php perfectly before - i replaced the oscommerce.gif with my own logo and everything was fine and dandy.

Then I had some contributions installed (paypal mod, STS, Order without account & image resize - none of which I would expect to cause this problem).

After the contributions, the image wouldn't change. when I edited and uploaded the file... I even took the image / tag out of the code and the old oscommerce.gif image still was there. Here's what the code looks like:

<td valign="middle"><?php echo '<a href="' . tep_href_link(FILENAME_DEFAULT) . '">' . tep_image(DIR_WS_IMAGES . '', '') . '</a>'; ?></td>

... and it doesn't affect a thing.

THe only luck I had was renaming my logo "oscommerce.gif" and uploading the image. Which is fine, but now it says "osCommerce" when you mouse over it. - I would rather have control of it and know how to fix this problem.

Any and all help is much appreciated.

Thanks!
