Holder.js in Google Appengine (python)

Question

I want to load a placeholder image using holder.js in a static template. In static template index.html I have:

<img src="/static/holder.js/200x200">

I have handlers set in app.yaml for serving static files in a folder called static, so I know that's not a problem, but for some reason holder.js will not generate the 200x200 image I called for (the log files generate a 404 error). I bet this is some sort of handler issue; perhaps App Engine is treating my request as a directory and cannot find it. I need to configure the app.yaml file so that it treats requests to holder.js as a parameter for the file and not as a subdirectory of the file. Can someone point me in the right direction to help solve this problem?

Do I have to do add a script handler separately from the directory handler? — user3059347

No, I meant in your template. Do you have <script src="/static/holder.js"></script>? — Daniel Roseman

Yes, I do have the script included. Does its position in the document matter? — user3059347

It shouldn't. What happens if you go directly to /static/holder.js in your browser? — Daniel Roseman

When using Holder.js, the src attribute isn't meant to be used as a real URI. Instead, it's used as an identifier for Holder.js (specifically the domain option). Your code should look like this: <img src="holder.js/200x200"> or <img data-src="holder.js/200x200">. Make sure to include <script src="/static/holder.js"></script> in the document as well.
