Hi David Lobato.
Welcome to Microsoft Community.
In your description, you can't see the image of the attachment when you add it using Gmail. What image are you not seeing? Or you can't find the attachment you need to add?
Since this is a Gmail issue, please log in to your Gmail account via the following link and then provide feedback in Gmail

Meanwhile, I also noticed that you are using IObit Unlocker to delete the files in %temp% path, and then you get a blue screen.
The %temp% path usually holds temporary system files that sometimes support the normal operation of the system, and they usually delete themselves when they are no longer needed. Therefore, there is no need to manage or delete them manually.
When some temporary files are being accessed or read/written, these files cannot be deleted. If you use other tools to delete them, make sure that it will not affect the normal operation of the system before you delete them. If you force to delete it, it is likely to cause system abnormality, such as occurrence of blue screen.
If you have problems using IObit Unlocker, please contact IObit Unlocker's online support via the link below.
