Here are a few options for describing the “付費圖片” (Fùfèi Túpìan – Paid Images) WordPress post tag in Traditional Chinese, with varying levels of detail:

**Option 1 (Concise):**

* **描述 (Description):** 包含購買或授權使用的圖片。

**(Translation: Containing images purchased or licensed for use.)**

**Option 2 (Slightly more descriptive):**

* **描述 (Description):** 標示需要付費才能使用的圖片資源，包括照片、插畫、向量圖等。

**(Translation: Denotes image resources that require payment for use, including photos, illustrations, vector images, etc.)**

**Option 3 (Emphasis on legal implications):**

* **描述 (Description):** 用於標記已購買版權或經過授權使用的圖片。請務必遵守相關使用條款，避免侵權。

**(Translation: Used to mark images for which copyrights have been purchased or usage has been authorized. Please be sure to adhere to the terms of use to avoid infringement.)**

**Option 4 (Focus on benefits/usage):**

* **描述 (Description):** 分類已付費取得使用權的圖片。這些圖片通常具有更高的品質和商業用途授權，適用於專業的設計和出版。

**(Translation: Categorizes images for which usage rights have been paid for. These images often have higher quality and commercial use licenses, suitable for professional design and publication.)**

**Which option to choose:**

* Choose **Option 1 or 2** for brevity and clarity.
* Choose **Option 3** if you want to emphasize the importance of respecting copyright.
* Choose **Option 4** if you wish to highlight the advantages of using paid images.

You can customize the descriptions further based on your specific needs and the type of content you are publishing. Remember to apply the description directly in the appropriate field when creating or editing the tag in your WordPress admin panel.
