img2md

• Automatically detects the MIME type of the image (e.g., image/png, image/jpeg).
• Encodes the image to base64 and outputs it in a single line.
• Generates a complete HTML <img> tag with the base64-encoded image for embedding in Markdown or HTML files.
• Automatically copies the generated tag to the clipboard using cliphist.
• The script handles large hashes by using a temporary file to manage clipboard operations.

Requirements

• Bash (Unix/Linux environment)
• file command (for detecting MIME type)
• base64 command (for encoding)
• cliphist (the clipboard manager that I'm using)

Installation

1. Clone the repository or download the script.

2. Make the script executable:

   chmod +x img2md

Tip

Move the script to a directory in your $PATH for easy access:

sudo mv img2md /usr/local/bin/

Usage

• Just run the script with the image as argument:

img2md <image-file>

• This will output:

<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUg..." alt="image" />
