Not sure if another solutions has been found, but I've been trying to get NextGen to work without success. Doesn't seem to be very non-techie-user-friendly, at least for this purpose.
I want to post a series of sponsors' logos on a page and have each one link to each sponsor's respective website. To make it easy for others to create these, I want to use the built-in WP Gallery to grab and arrange these logos in a nice clean layout from images uploaded to the Media library.
I've created a gallery ( here ) but can't set the individual images to link externally. The only options seem to be to the file themselves or attachment pages. Even with external links put in the Link URL field of an image when I upload it, there doesn't appear to be a way to chose that when putting it in the Gallery. I can only make them link to the file or to an attachment page.
Seems like a simple fix.... a third option in the Gallery creator to send a clicker to the Link URL associated with an image.
Please tell me this is possible.
