Actually it can be many things. And yes, the problem is on the sending side,
not the receiving side. There are several things the sender can do to reduce
the file size:
- First of all use a file format that is compressed. Most people do that
anyway by sending e.g. JPG, but maybe someone is actually trying to send BMP
or RAW.
- Second choose a picture dimension that is appropriate for the viewing
device. If viewing a photo on an old 800x600 monitor or even worse a 640x480
picture frame then there is no point in sending a 3900x2600 picture (unless
you expect to zoom in into that much more details).
- And third choose a lossy compression rate that is appropriate for the
purpose of the photo. If it's just a snapshot to look at and then forget it
then a compression setting with a high loss is probably quite acceptable. If
it's a picture you intend to print and frame then you may tolerate a larger
file size in favour of less loss due to compression.
Anyway, in case your friend is using Windows and Office then Outlook will
allow her reduce the picture dimensions and file size according to the
intended purpose when attaching the file to the email.
And of course any decend photo editor software will support exporting of
photos in different dimensions and compression rates.
