From past experience and i may be getting muddled a bit but do not think so.
Open MSPaint and open the jpeg image with that. Crop it a little and save as a BITMAP image (.bmp)
I used to send back files (pics) in that format after they started as jpeg.
About 1mb is fine and only takes a short while to be seen by recipient.
No doubt someone will have a better option but have a go and see if it works.
