Image handling help

[jcran]

I have a database that I need to process images from. The database has 2 fields for images, one is the number of images the other is a link to the first image.

For example, if the number of images = 5 and the image link is http://www.website.com/image.jpg then the script would need to do this.

Show the first image from http://www.website.com/image.jpg and parse out the other 4 images like so;

http://www.website.com/image2.jpg
http://www.website.com/image3.jpg
http://www.website.com/image4.jpg
http://www.website.com/image4.jpg

The problem is, the images will be located in several different places on a different server and the image type could be .bmp, .jpeg, .gif and so on.

Can anyone help on this one? Thanks, Jason

Additional details:

The field that has the number of images could be anywhere from 1 to 10. This field is just telling how many photos are associated with this listing. Then, the other field is the link to the first photo. So, if there is only 1 photo, basically nothing needs to be done. But, if there are more than one photo, the script would need to add additional links to those photos. The photos will always be in the same directory, for a given listing, but the name of the photo would have a 2 3 _4 and so on, added to the end.

What I meant by different places is; one listing may have photos in http://www.website.com/photos/somethingelse/blahblah/photo.jpg and another listing may have photos in http://www.website.com/photos/somethingelse/anotherdirector/photo.jpg

The photos for each unique listing will all be in the same directory though, but will have _# added to it.

For example if one listing has 3 photos, the first link will read http://www.website.com/photos/somethingelse/blahblah/photo.jpg and the script will need to create the other two links to be http://www.website.com/photos/somethingelse/blahblah/photo_2.jpg and http://www.website.com/photos/somethingelse/blahblah/photo_3.jpg

Hi,

I am making an assumption with respect to your database query in terms of variable names used:

// $numberOfImages is the first field
// $link is the second field

// Get extension of image including the .
$ext = strrchr($link, ".");
// Extract the first link to the image excluding the extension
$orgLink = substr($link, 0, strripos($link, '.', 0));
// loop over the additional images
for($xNr=2; $xNr<= $numberOfImages; $xNr++)
{
	// These are the additional image links
	$nextLink = $orgLink . '_' . $xNr . $ext;
}

This is just to give you an idea on how to create the additional links, i.e pure string manipulation. I noted that you switched numbering syntax from fileNameX to fileName_X but it is easy enough to adapt.
