Image Hosting

From v2.8, VNote supports several image hosting services. Now VNote could upload local images to cloud services.

There are 4 services now VNote supports:

For each service, you need to configure the service provider and provide some kind of tokens to VNote to enable VNote access the service.

There are two common options for each service:

Keep image scale: Whether keep the scaling of the images in the new links;
Copy the new content instead of replacing: After uploading images, just copy the content with new links, without touching the original file;

Configurations

For GitHub, you need to provide:

Personal access token: Go to the Settings of GitHub, then Developer Settings, then Personal Access Tokens, and generate a new token with full control of repo.
Repo name: Name of the repository in GitHub to hold your images;
User name: User name of GitHub;

Gitee is quite the same as GitHub.

Go to Wechat Public Platform, then Development, then Basic Settings, and get your AppID and AppSecret.

One more step is to write your IP address into the IP Whitelist to allow uploading images from your local host.

The markdown2WechatToolUrl is a link which you want VNote to open automatically after copying the new content.

Go to Tencent Cloud Platform and select the Object Store product;
Go to the Keys Management and generate a new API key (SecretId and SecretKey);
Go back to the Object Store panel and select the Store Bucket List to create a store bucket (with the Access Permission being Public Read Private Write);
Click the Basic Settings on the left and get the Access Domain;
In the same page, add a rule to the CORS Settings;

After you finish writing a note, you could choose to upload images to image hosting service in the context menu (in Edit mode).

VNote will go through all the local images and upload them to chosen service.

If you choose to replace image links in the original file, the content will be modified after finishing uploading. VNote will prompt to delete unused local images when you save the note.
Otherwise, VNote will copy the new content with new image links and leave the original note untouched.
