org-mode Inline Image Fix

This repository is a collection of fixes related to the image display feature in org-mode.

All the fixes are done by force using advice and cl-letf, so there is a possibility that it will not work due to the version upgrade of org-mode.

Data URI Support(org-datauri-image.el)

• Display data URI link as inline image
• Export data URI (HTML backend only)

Setup

(with-eval-after-load "org"
  (require 'org-datauri-image)
  (org-datauri-image-activate))

To use display inline images only:

(with-eval-after-load "org"
  (require 'org-datauri-image)
  (org-datauri-image-activate-display))

About registration to package distribution systems

For various reasons, it is difficult for me to register packages with the package distribution systems (package archives).

If you wish to register this package with the package archives, please feel free to fork this repository and proceed with the registration and maintenance on your own. No permission is required.

The reasons are that communication in English is a burden, it is not necessary for me, It is fair for those who need it to bear the cost, I want to reserve the right to develop in a free coding style, etc. .

If someone else creates a better solution, I will gladly use it. Ideally, the original project should be improved so that a need for this does not arise, but please don’t expect me to negotiate for that.

From someone who took hours using translation software to write this section.
