getimage size error

[Lassie]

I have a program which creates a gallery of thumbnail images. Whe selected the selected image is shown.

I have this working on my localhost machine but I get the following error on my server.

Warning: getimagesize(./images/gallery/) [function.getimagesize]: failed to open stream: Permission denied in W:\www\e_cart19\browse_cats.php on line 54

I have the gd functions enabled and the database connections are fine.

Could anyone point me in a direction investigate please.

From the error - "./images/gallery/" That is not a path/filename. It appear like the filename part is missing from the end. Find out what would cause your code to drop the filename. I suspect that your code is dependent on register globals. You would need to post your code if you want help on what it is doing.

Thanks for coming back

The code is as follows. The file is appended as $mainImage.
