Image attachments display

Hi, I would like to know how I can configure the program so it doesn’t show me the images attached in an email.
I have a png image as signature and in the mails it shows the image as the signature AND as an attachment below the signature, thus duplicating the image. Others attached images are also shown and I would like to disable this. It is possible?

I’ve also seen that other people already complained about the signature images being shown as attachments, is this not fixed yet?
