When i add images to slider, i must always upload images to my host. For example; i want to show "http://www.google.com/images/nav_logo7.png" image directly in slider without self-host. Simply how i can do it? Thanks, regards...

Re: How can i show external/3rd party images in slider?

You need to add a URL field for this image to your CCK content type and view and use this field in the preprocess function in the template.php file instead of the image field.

Hope this helps you further, please let me know.

Thanks for the answer. First

Thanks for the answer. First off all i must specify that i am a starter at drupal. i can add url field but i do not know how can i edit my template function? can you write a "how to note" about that?

My template function is: http://pastebin.com/m5851b8ff

Default function which i edit for my template: http://pastebin.com/m3699c0a8

Thanks, regards...

Re: Thanks for the answer...

I have added the code to both preprocess functions.
// add image from URL and
// add pager item image from URL
You need to change the fieldname of the URL field you use.
