When downloading pictures, the octopus collector can customize the naming method of pictures by setting file name rules. The specific operation steps are as follows: 1. Open the octopus collector and create a new collection task. 2. In the task setting, select the URL to be collected as the starting URL for collection. 3. Configure the collection rules. You can use the intelligent identification function to let Octopus automatically identify the data structure of the page, or set the collection rules manually. 4. If you set the collection rules manually, you can select the picture elements on the page with the mouse and set the corresponding collection rules to ensure the correct acquisition of the required pictures. 5. When setting the image download path, you can click the "Settings" button and select the "Custom File Name" option in the pop-up dialog box. 6. In the input box of custom file name, you can use variables to name the file name of the picture. For example, you can use the {Title} variable to represent the title of the picture, and the {Serial Number} variable to represent the serial number of the picture. 7. After confirming that the settings are correct, you can start the collection task and let Octopus start collecting and downloading pictures. By setting file name rules, you can name a picture file according to its specific attributes, which is convenient for subsequent management and use.
