16.4.7 Showing BLOB Images in Interactive Grid

An Interactive Grid has no native Display Image column type. To show an image in a row, use an HTML <img> tag with a src URL the browser can fetch and render inline.

The GET_BLOB_FILE_SRC function in the APEX_UTIL package generates the URL you need. Alternatively, you can serve the inline BLOB images from a custom page.

• Using GET_BLOB_FILE_SRC for Image URL
  Build an image URL with GET_BLOB_FILE_SRC and display it in an Interactive Grid using a generated img tag.
• Configuring Reference Image Page Item
  Use a BLOB-backed form item to let GET_BLOB_FILE_SRC infer the file metadata for an image URL.
• Serving Inline BLOB Images with a Page
  Serve an inline image from a page process by calling APEX_HTTP.DOWNLOAD with the image ID.
• Using an Inline Image Serving Page
  Generate an image URL with APEX_PAGE.GET_URL and pass the image ID to your image-serving page.
• Weighing X01 Against a Secure Page Item
  The X01 parameter is convenient, but not checksum-protected. Understand the potential risk of using this parameter to decide if a secure page item is more appropriate for your use case.
