I have an instance of Joomla with the Phoca Gallery component installed. I have recently modified this component extensively. I have the gallery setup with a layout like the attached file.
What I need is for the main image to be clickable and a larger version of the image is shown in either LightBox or ThickBox WITH the left and right arrow navigation being active so they can scroll though the images straight from LightBox/Thickbox.
When I modified the gallery to appear like the attached screen shot I used the "large" image that Phoca Gallery makes. By Default, Phoca Gallery creates 3 sizes of images when the images are uploaded : Small, Medium & Large. You will have to make the LightBox/ThickBox utilize the Large image, use the Medium image where you see the larger image in the attached file and then the small image in the right hand layout.
I need the large LightBox/ThickBox image image to be about 800px wide.
So the thumbnail for the right hand Gallery
Medium image when the Thumbnail is clicked it will show in the iframe I currently have the large image showing in
The Large image in LightBox/ThickBox
Please let me know if you have any questions.
