SuperMap iPortal provides a default thumbnail configuration function for you to configure unified thumbnails for maps, services, data, apps, and insights. After configuring the default thumbnails, all the resources added to the portal will use the default thumbnails. Of course, you can also edit the thumbnail of a single resource by editing its basic information.

Steps to configure default thumbnail:

Log in to the portal home page as an administrator, and select "Management"> "Resource Center Management"> "Thumbnail Configuration" to enter the Thumbnail Configuration page. Here we take the default thumbnail configuration of service resources as an example:

1. Click the "Replace Thumbnail" button.
2. Select the thumbnail file to update.
3. Click the "Save" button to complete the configuration.

Note:

• Acceptable thumbnails formats: JPG, PNG.
• Image size can't exceed 1M.
• Recommended image size: 265 * 170 px.
