2. Optional Configuration

• Upload Channel: Choose telegram, cfr2, s3, discord, or huggingface
• Channel Name: Specify a concrete channel instance in multi-channel deployments
• Chunk Size: Always shown. Telegram defaults to 16MB, Discord to 8MB, and other channels default to 0. 0 disables chunked upload

2.2 Advanced options

• Excluded Remote Domains: Supports commas or new lines. Remote images from these domains are skipped to avoid duplicate uploads
• Auto-exclude Current Image Bed Domain: The hostname from API URL is always excluded automatically
• Backup Path: When local backup is enabled, the backup path also supports placeholders

2.3 Placeholder reference

${noteFolderName}	Name of the folder containing the current note	Projects
${noteFolderPath}	Full folder path of the current note	Notes/Projects
${noteFilePath}	Full path of the current note	Notes/Projects/weekly-report.md
${originalAttachmentFileName}	Original attachment file name without extension	image
${originalAttachmentFileExtension}	Original attachment file extension without the dot	png
${date}	Current date, default format YYYYMMDD	20260327

• ${date}, ${time}, and ${datetime} support momentJsFormat, for example ${date:{momentJsFormat:'YYYY-MM-DD'}}
• Multiple placeholders can be combined, for example ${noteFileName}-${datetime}-${originalAttachmentFileName}
• In custom naming mode, the actual behavior is: rename the file from the template first, then upload it using the original-name mode

Common template examples

• Custom file name template: ${noteFileName}-${datetime}-${originalAttachmentFileName}
• Upload folder: ${noteFolderName}/${date}
• Backup path: backup/${noteFolderName}/${noteFileName}

Android/iOS Devices

API Configuration

This plugin uses CloudFlare ImgBed's upload API with the following parameters:

• Endpoint: /upload
• Method: POST
• Authentication: Upload auth code, or API token with upload permission via Bearer token
• Content Type: multipart/form-data

Chunked upload behavior

• Telegram: default chunk size is 16MB
• Discord: default chunk size is 8MB
• Other channels: default chunk size is 0, which disables chunked upload
• HuggingFace: usually supports large direct uploads without client-side chunking
• Cloudflare R2 / S3: usually do not require client-side chunking

The plugin automatically decides whether chunked upload is needed according to the selected channel and file size.

For detailed API documentation, please refer to CloudFlare ImgBed official documentation.
