Functional Architecture for Knowledge Abstraction and Surrogation
Published in Denise Bedford, Knowledge Architectures, 2020
Thumbnails are another kind of descriptive surrogate. We’ve chosen to categorize them as a descriptive surrogate rather than as a summary or a gist because new value was added to the source asset in creating the surrogate. Thumbnails are reduced-size versions of pictures or videos, designed to help us better understand, recognize, and organize them. They serve the same role as a descriptive abstract of a paper or book. Just like targeted text extracts might be used to boost a search index, so might thumbnails support visual search. These descriptive surrogates also serve one of those crucial goals of providing a sense without having to download the full asset. They are also essential surrogates when there is only one copy of the visual asset, and it is under protection or conservation status. Also, consider the informative images we create to describe art or image collections. To generate this surrogate, we select a representative set of images from a larger set of images. Another form of descriptive surrogates of physical objects is photosculptures, or photographs of physical artifacts. This type of descriptive abstracting often involves taking multiple photographs or representations from different points of view. These surrogates describe an asset that requires artistic and creative interpretation to produce.
Creating the Web Site
Published in Tom Hutchison, Paul Allen, Web Marketing for the Music Business, 2013
Thumbnails of photographs are popular on web pages. A thumbnail is a small version of a picture that opens a larger graphic file of that picture when the user clicks on it. Most web design programs will automatically create thumbnails with a simple command, but the concept is simple enough to create with a bit of HTML text. First, open the photograph in any photo editing program. Reduce the size of the photograph to the ideal thumbnail size (maybe 150 pixels wide by 200 pixels high). Be sure to resample the resized photograph (thumbnail) for best results. Save the new photograph under a different name so that it won’t overwrite the original. A good rule of thumb is to use the same name but add “_ small” to the name or “_thm” so you can distinguish it from the original. Then when creating the web page layout, include the smaller thumbnail-sized photo on the page. Create a hyperlink that will lead to and open the larger graphic file. The HTML may look something like that shown in the box below.
Histology Image Viewer and Converter (HIVC): a high-speed freeware software to view and convert whole slide histology images

HIVC is fully operated through its Graphical User Interface (GUI). Users can add WSI files or a folder containing several WSIs. All images can be loaded into the software and represented by thumbnails. For each WSI, the software shows the embedded associated images of the label, thumbnail, and a macro-slide view. The user can click on each image, which allows viewing in a separate window with more details. The histology image metadata such as file name, width and height in pixels, resolution in microns per pixel (mpp) and pixels per millimetre (ppm) are read from the WSI and shown next to the thumbnail view. The user can also change the name of the WSI file and the output images as desired. The conversion settings panel on the right allows the user to configure zoom (i.e. 10×, 20×, etc.), image format, compression quality, destination path for converted images, and options to modify the file names. After finalising the settings for all loaded SVS and TIFF files, the convert button initiates the conversion process for all files according to the specified settings (Figure 2).
