UMAX Astra 3450 - can't e-mail jpg pictures

Question

hi...I have an old Astra 3450 that I am using to scan some pictures. I have set jpg as the file format under preferences....I have successfully scanned all the pictures...the problem is when I try to upload the picture so I can e-mail it (using hotmail account). It does not upload the picture. Any idea what is going on? I need help. Thanks,
