This text filter rewrites the src attribute on img tags that only specify a filename to point at the current location of an attached image with the same filename should one exist.
That is, if you put this:
<img src="zebra.jpg"/>
And you've uploaded a file called zebra.jpg to an image field on the same entity, the module will replace it with something like:
<img src="/sites/foo.com/zebra.jpg"/>
I find this works quite well with Markdown. I can usually remember the filenames or know what I'll call them when I get around to uploading. From there,  is pretty handy.
Why?
My hope is to improve on other methods of placing images in-line which, so far as I can tell, fall into two categories:
- Bypassing Drupal entirely and using a JS file manager of some sort to upload images directly and then referring to them in
img tags with /sites/brittle_path/files/image.jpg
- Using a magic token that refers to the field id and often encodes some position, style, etc.
I like my images being available to Drupal. Not just pointed at in code but rendered as a field, with different Image Styles, that can be included in Views, change with Context, etc. Rules out the first one.
DDEV is the official local development tool of Drupal. And like Drupal, DDEV depends on the support of the open source community.
