We are aware of an issue that has arisen from the recent 8.1 release, specifically around: "#798: Enhanced the file manager with the ability to move files between folders, eliminating the need to delete and re-upload files."

This has resulted in the 'Select' button not always appearing in the File Manager in some circumstances when you select an image to insert into content.

We have a fix for this which will be released soon, in the meantime you are able to override the setting yourself in order to see the 'Select' button.

How to:

1. Add this file to your project as a view override in \Views\FileManager https://github.com/cloudscribe/cloudscribe/blob/develop/src/cloudscribe.FileManager.Web/Views/FileManager/BrowsePartial.cshtml
2. On line 192, change 'data-can-select="false"' to be 'data-can-select="true"'
3. Save and release to your site in the usual way
