A Thumbnail Post is a specific type of webpage where many of the images on the page are small "thumbnail" sized images which are direct links larger versions of the same images. Registered users of Image Surfer Pro can add all of the the linked larger images to their fusker collection with a single click of the button.
When clicked the button will check the current browser file and look for images which link to other image files. When such links are found, the image linked to will be added to the fusker collection.
Not every page which looks like a thumbnail post has direct links to other images...
If Image Surfer Pro does not find any matching links on the webpage, you will be informed that
the page does not appear to be a thumbnail post with the following dialog.
You can use the button to create a page which will show you the link which Image Surfer Pro found associated with each image. In fact, the button is exactly equivalent to configuring "Auto select URL links to images in forms" using then using the button to generate a form for the page and then processing the form with the button.
Auto Ranging is not utilized when adding images to the fusker collection this way, so only those images directly linked to by the webpage will be added. If you have chosen to automatically build lists from individual images added in the same directory it is likely the linked to images will form one or more list fusked files. After any matching links have been added to the fusker collection, a visualization of the last image segment added will be displayed in the browser window.
