@title{Images}

Entering images in-line is simple. Use @literal|{@image["filename.jpg"]}| to insert an image file into your document. The image file must be stored in the same directory/folder as your scribble file. If you want the image centered with your text, you can use @literal|{@centered{@image[filename.jpg]}}|

@codeblock|{@image["KaranisKM3338_1.JPG"]}|
@image["KaranisKM3338_1.JPG"]

The image will appear at the size of the image file. There are a few ways to modify size. You can scale the image using your preferred image manipulation program:
@codeblock|{@centered{@image["KaranisKM3338_1scaled.JPG"]}}|
@centered{@image["KaranisKM3338_1scaled.JPG"]}

Or you could use CSS or LaTeX to scale the images. This requires more effort in coding, but it can be universally applied to all of the images you use so you don't have to manually re-size all 50+ images in your dissertation and you don't need to either scale the original image files or have double copies of all of your images. Setting up a CSS or LaTeX style sheet is outside the bounds of this tutorial, but I will cover how to incorporate it into your scribble file. First you need to first make a CSS/LaTeX stylesheet and store it in the same directory. Then you can define a function to apply the added style 

@;codeblock|{@(define (scaled-centered-image path . content)
@;   (centered
@;     (apply image 
@;            #:style (make-style "width-constrained-image"
@;                                (list (make-css-addition "extra-style.css")))
@;            path content)))}|

@;(define (scaled-centered-image path . content)
@;   (centered
@;     (apply image 
@;            #:style (make-style "width-constrained-image"
@;                                (list (make-css-addition "extra-style.css")))
@;            path content)))



@;This function constrains the image to the width of the text in HTML and centers it. In order to apply it, call on the function you've defined above @literal|{@scaled-centered-image["filename.jpg"]}|

@;codeblock|{@scaled-centered-image["KaranisKM3338_1.JPG"]}|

@;scaled-centered-image["KaranisKM3338_1.JPG"]

@;Note that this is the same file as at the top of this section, the image file itself has not been altered.

@section{Figures}

In an academic paper, you will likely have more than one image, and perhaps other types of figures such as tables and graphs. Additionally, your images and figures will need to be numbered and tagged in such a way that you can refer to them in your text. For this we use the @literal|{@figure}| function.

@codeblock|{@figure["tag" @elem{Image identification} @image["filename.jpg"]]}|

This function has three primary arguments:

The "tag" is the what you will use to reference the figure when you reference it in-line. This argument requires a string, so enter it in quotation marks. You can use any tag convention you prefer, but each tag must be unique. I am using the Site + Museum number convention here because the artifacts I'm discussing already have unique ID numbers and that's the convention that I've used for naming the image files.

The @literal|{@elem{}}| argument is for any text you want visible after the figure number. This will likely include a description of the image, date, culture, materials, photo credits, etc.

The @literal|{@image["filename.jpg"]}| argument is to place the image.

To reference a figure in-line, use @literal|{@Figure-ref[""]}| if you want the 'F' capitalized or @literal|{@figure-ref[""]}| if you want the 'f' lower-case. Since each figure has a unique tag, you can reference a figure multiple times. The figure number that appears in-line will have a link to take you to the figure itself. Unfortunately, since a figure can be referenced multiple times, it's impossible to have a link to reference back to your exact location within the text. Unlike the bibliography, the figure list will render whether or not the figures have been referenced in your text. 

The figures themselves will appear wherever in the order you define the figure functions. Depending on your preferences, you can intersperse the images within the text or group them together. The Racket/Scribble code for figures generates the figure numbers based on the order the functions are defined, not the order in which they are referenced in the text. If you edit your paper and end up referencing figures in a different order, you can update the figure numbers by re-organizing the order in which they are listed.

include loom weights of unfired clay (@Figure-ref["KaranisKM3338"]), or
