+### 2) 方案 A：让搜图结果可拿到可访问 URL（写入 CustomContent）
+
+由于腾讯云 TIIA `SearchImage` 的返回 `ImageInfos` 默认不包含 `ImageUrl`，因此无法直接从结果拼出可访问 URL。
+为便于前端展示/回查，上传入库时将“可访问图片 URL”写入图片元信息中：
+
+- `api_v1/utils/tencentcloud_tiia.py`
+  - `upload_image_url_to_tencent_tiia(...)` 调用 `CreateImage` 时：
+    - `CustomContent` 默认写入原始 URL（`CustomContent` 文档上限 4096 字符）
+    - `Tags` 默认不写入（避免触发“标签值长度过长”）
+
+前端取值建议：
+
+- 若腾讯云 `SearchImage` 返回的 `ImageInfos[i].CustomContent` 可用，则直接作为可访问 URL 使用
