How Can I Increase The Size Of The Thumbnails For This Script?

I have a page shown here that uses a modified PrettyPhoto gallery. The modification is for it to show a thumbnail view of the other images within the same gallery along the bottom of the overlay image. Works well for me, but the client is unhappy about the small size of the thumbnail images. I am looking for some input on how I would be able to increase the size of these thumbnail images.

I have tinkered around with the image source width (around line 243):

toInject += "<li class='" + classname + "'><a href='#'><img src='" + img_src + "' width='80' alt='' /></a></li>"

but a new issue arose regarding the last thumbnail image being cropped inside the div .pp_gallery. The script seems to dynamically choose how many thumbnails will fit inside the allotted space. How can I increase the thumbnail sizes and ensure that the thumbs won’t be cropped off?

FYI, here is the complete version of the script:

Look at the _insert_gallery function, itemWidth, navWidth, itemsPerPage, in the original script. That would be function C() in your script.


		function _insert_gallery(){
			if(isSet && settings.overlay_gallery && _getFileType(pp_images[set_position])=="image") {
				itemWidth = 52+5; // 52 beign the thumb width, 5 being the right margin.
				navWidth = (settings.theme == "facebook" || settings.theme == "pp_default") ? 50 : 30; // Define the arrow width depending on the theme
				
				itemsPerPage = Math.floor((pp_dimensions['containerWidth'] - 100 - navWidth) / itemWidth);
				itemsPerPage = (itemsPerPage < pp_images.length) ? itemsPerPage : pp_images.length;
				totalPage = Math.ceil(pp_images.length / itemsPerPage) - 1;

				// Hide the nav in the case there's no need for links
				if(totalPage == 0){
					navWidth = 0; // No nav means no width!
					$pp_gallery.find('.pp_arrow_next,.pp_arrow_previous').hide();
				}else{
					$pp_gallery.find('.pp_arrow_next,.pp_arrow_previous').show();
				};

				galleryWidth = itemsPerPage * itemWidth;
				fullGalleryWidth = pp_images.length * itemWidth;
				
				// Set the proper width to the gallery items
				$pp_gallery
					.css('margin-left',-((galleryWidth/2) + (navWidth/2)))
					.find('div:first').width(galleryWidth+5)
					.find('ul').width(fullGalleryWidth)
					.find('li.selected').removeClass('selected');
				
				goToPage = (Math.floor(set_position/itemsPerPage) < totalPage) ? Math.floor(set_position/itemsPerPage) : totalPage;

				$.prettyPhoto.changeGalleryPage(goToPage);
				
				$pp_gallery_li.filter(':eq('+set_position+')').addClass('selected');
			}else{
				$pp_pic_holder.find('.pp_content').unbind('mouseenter mouseleave');
				// $pp_gallery.hide();
			}

I modified those settings and had to modify the CSS as well to get the thumbnails larger. But now the thumbnails are still being cropped. Take a look at the link below and let me know if there is a solution to ensure that the entire thumbnail would be visible.

In function k(t) you still got the old values.


                itemWidth = 52 + 5;
