The error message you are seeing occurs because Excel does not embed images directly, rather it links to the location of the image on your system. This means if you move or delete the file, or if you share the Excel document with someone else and the image doesn’t come along with it, Excel cannot find the image and thus cannot display it.
You could solve this issue by:
- Instead of attaching the screenshot, you could insert the image into the cell; Excel should then embed the image fully into the file and you should not have issues sharing it. Use “Insert Picture” option in Excel for this. Check what is the VBA code for that.
- Alternatively, you can try using a custom activity or a custom code to transform the image to a base64 text and use that text in the excel. Then the next user can get that text and reconstruct the image back.
