Globally Managed Dynamic Images

Globally manage image width and captions from a central _data/i_Images table allows non-technical users to easily place images anywhere in a Doc and globally change the Width and Caption.

This is in response to a post on the Coda Community at:

https://community.coda.io/t/embed-and-image-formulas-dont-work-in-concatenate-formulas/17375⁠

⁠

It expands on my previously published
“Global Components Example”⁠

For this demo, I’m using images from SquareSpace’s CDN (because the original post used the Whale image from SquareSpace).

But you could modify this to work with most any Image CDN that provides a URL-based API for serving dynamically sized images.

⭐ If you’re interested in this approach, I would highly suggest looking at

Cloudinary⁠

for your media management and CDN. ⭐

Dynamically placed and sized image

The image below was placed by pasting the code copied from the Copy This Code column on

@Whale⁠

row of the

ImgTable⁠

on the

i_Images⁠

_data Page.

If you select a different width from the imgWidth column, it will change the size of the image on this page.

Currently, the selected imgWidth is

500

⁠

If you edit the imgCaption column, it will change the Caption below the image here.

House on the Lake⁠

demo page for how you might use this in a production environment.
