Hello filers!

We've been seen a rise in some issues related to images in filings. To help you stay ahead of these, and resolve them quickly, we wanted to provide some tips for you below. But first, here's the details.

SEC Image Requirements

All images filed with EDGAR must be in GIF or JPEG format. However, while EDGAR HTML document’s images are not actually validated, documents containing iXBRL have additional image format requirements. XBRL filings with non-compliant images will be suspended with errors that can be pesky to resolve.

How to Resolve Validation Errors

Here are some tips and tricks to help work out those errors quickly so you can submit your filing!

First, here are some examples of common XBRL image errors:

ERR:  ERROR_CONDITION
MSG:  Submission with Inline XBRL attachment is invalid if it fails XBRL Validation.
LOC:  LINE NUMBER: 0

WRN:  XBRL_VALIDATION_ERROR
MSG:  XBRL documents contain following XBRL validation error(s).
LOC:  LINE NUMBER: 0

WRN:  XBRL ERROR MESSAGE
MSG:  Error: [cp-0502-Prohibited-Html] InlineXBRL references a graphics file which has invalid format 'xyz-20230308_g1.jpg' for <img>. xyz-20230308.htm line 4 
LOC:  LINE NUMBER: 0

You may also see EFM.5.02.05.graphicFileContent validation errors. Many of these file content errors are caused by metadata contained in JPEG files but may also be due to the image not being GIF or JPEG format, despite the filename extension.

If your filing has these errors, there are several ways to address the problem.

1. Ensure that the image is truly either in GIF or JPEG format. An easy way to check this is to open the image in Notepad and look at the first few characters. GIF files will start with “GIF”, JPEG files will start with unusual characters such as “ÿØÿá”, and PNG files start with “PNG”. XBRL validation may also indicate “Image files must be GIF or JPG format”.
   
   If the image is actually a PNG or other unsupported format, you can use Paint or other image processing software to convert it to GIF (best for logos, charts, and images with few colors) or JPEG (best for large, colorful images) formats. Converting the images may reduce the quality of the image, so ensure that you are satisfied with the output image. 
   
   
2. For JPEG images that still fail with XBRL graphicFileContent validation errors, removing image metadata will often resolve the issue. In Windows, right click on the image, select Properties, then go to the Details tab. Click the Remove Properties and Personal Information link at the bottom of the dialog, then in the Remove Properties dialog, select Remove the following properties from this file, click Select All, and finally click OK. 
   
   After removing the properties, locate the image in the Wdesk document, remove it, and replace it with the modified image.
   
3. For a large number of images or where removing the properties doesn’t work, the free ExifTool utility is available for many operating systems.  To use this, create a new folder and copy the ExifTool executable and all of the images into it.  Create a new text file in Notepad and paste the following line:
   

   "exiftool(-k).exe" -xmp:all= -all:all= -icc_profile= -overwrite_original *.jpg

   Save the file into that folder, named unxmp.bat and double click unxmp.bat to start the metadata removal process.  Removing metadata from images will generally not affect their appearance, but verify that all of the images look as expected.  Find and replace all of the affected images in the Wdesk document with the images in this folder.
   
   
4. If none of these methods are able to resolve the graphicFileContent issue, another option is to resave the image, using Paint or other image software, to a new JPEG.  This will reduce the image quality so only should be done as a last resort.
