Getting to grips with pic sizes

Good morning folk,

I am a puzzled by the disparity in size I get for any given pic between My
Docs & email. I have just taken one of my pix from My Docs and inserted it
into an email in Outlook Express...and sent it to myself.

When looking at it in My Docs - File - Properties it says
Size 68.2 kb
Size on disc 72.0 kb

When looking at it in Outlook Express - Inbox - File - Properties, it says
that the size is 94KB. That is almost a one third gain in size.

Most of my friends have telephone connections, and I just send pix for fun.
The last thing I want to do is burden them with long download times. Does
anyone have suggestions for socialable email sizes?

==================================
You are looking at the total file size
including the e-mail message. If you
click the paper clip and look at the
attachment you will see the file size
of the image. And if you save the image
back to your desktop you will see the
file size is the same as it was originally.

And...actually...even the 94kb should not
be a problem for a dialup connection.

If you wish to do some resizing...the
following freebie is a useful tool:

OK, go to the following link and download and
install: ImageResizer.exe

http://tinyurl.com/36n

Then you can open any folder that contains
images and you will have an option to resize.
Just right click the selected image files and
choose Resize Pictures from the menu. You
can select one image or a whole group.

The program will place the resized copies in
the folder with your originals.
(Tip: *Never* overwrite your originals)

BTW...when resizing if you go to...Advanced
Button / Custom...and enter 640 in each field...
that will be a good size for e-mail purposes.

John,
Thank you for your suggestions...

One thing though.
Re the resizing, I use a cheap
photo-editing prog, and resize when
exporting from that.

It would be great to have a rough
recipe though, concerning size and download time,
(or even several,if the ratio
is complicated)
eg 45 kb = -- secs 95 kb = -- secs
(or whatever.)

It would really help.

Best wishes,
Canna

Download / upload time is dependent
on your connection speed.

The difference in actual size (68.2kb) and the Size on Disk (72.0Kb) is
because the staorage of files on disk takes up a full sector even when the
data is less than the full sector size. On most new PCs the sector size
would be 4Kb. So the size on disk would be next multiple of 4Kb. In your
example the 0.2Kb out of file size of 68.2Kb takes up the whole sector of
4kb thus making up 72Kb.

The gain in emailed version is because of the mail headers + mime encoding
used for sending the mail message. It uses 7bit encoding to encode binary
data such a picture. So expect a gain of more than 1/8 because of just that.

To see the actual email message as pure file content, select the message in
OE and press Ctrl-F3 which will bring the Message source window. Scroll down
to see how your picture is represented in textual form.

Coming back to your original problem, I would suggest you use a service like
www.fotki.com. They give you some free space which you can use to upload the
photos and send the link around to all to view. If you cannot afford the
paid service then just delete old pictures to upload new ones. For more
options see:
