Inserting Images

[Douglas Lapp]

I am having trouble inserting images.  I have placed an image (.png file) into a folder I called "images" that is at the same level as my "source" folder.  When I use

<image source="images/file-name.png">

<shortdescription>Image Description</shortdescription>

</image>

the image does not appear, but just the Image Description and an icon for the supposed image.  Any thoughts on what I am doing wrong?  Thanks for any help.  Sorry I am such a novice at this.

Douglas - 

Your publisher file is likely pointing to a different directory than where you have placed the images.

See this page for more details:
https://pretextbook.org/doc/guide/html/processing-directory-management.html

Then check your publisher file to see where the directories element is pointing:
<directories external="../external"  generated="../gen" />

I was just writing when Andrew's message came in.  You probably want your figure in the directory "external/images".

Thanks, David and Andrew. So should I create a folder called external and place a folder inside of it called images where I will place the image?  Then I assume I look in the publication file for the directory pointer and edit it to say <directories external=“../external/images”?  Right now that is set at <directories external=“../assets” as was done from the GitHub template. 

Thanks,

Doug

<directories external="../assets" can be left.

With that name make a directory called "assets". Make a sub folder inside it called images. Put your images there (so what you said but changing to "assets"). Then everything will match.

Older versions called the directory "external" so many of us still have that name and we have that in our publication files. With publication files names are but noise and smoke (and tradition).

Thanks, Mark!  I am slowly starting to understand the architecture here.  I really appreciate everyone's help as I learn!

Hi Mark,

I tried this and am still not seeing an image appearing.  Here is what I entered:

<image source="images/descarte-fly.png" width="50%">

<shortdescription>Descarte's Fly</shortdescription>

</image>

I am using the "assets" sibling directory to the source folder that was originally created by GitHub when I used the template.  I placed a folder inside of the "assets" and placed the image inside of that folder.  I am not sure why it is not working.  Thanks for any advice.

[Sean Fitzpatrick]

The file should be in
assets/images/descarte-fly.png

Is that what you have? If so, rebuild the HTML just to be sure.

Hi Sean.  I think that is what I have.  Here is an image of my directories.

And could you share your publication file?  Or share a link to your GitHub repository and I can take a peek.

The next step is to look at your output folder and see if the image is in the right place.  And look at your output source to see where it is expecting the image.

Hi Oscar.  Nevermind.  I got it to work.  I had a typo on the file name.  Sorry for the bother.  BTW, when you go up for promotion and want a letter of support, I am your guy.  What you contribute to the community really is an asset to all of us!!!  Thank you for being there when we novices need it.

Cheers,

Doug

Glad it's working. And these sorts of "bothers" are really helpful to know where the pain points are and how we can support new authors better.
