Most labs will rescale any image large enough to print at 4x6 to either
fill the paper (with parts lost if the aspect ratio isn't 2:3) or have
white borders and fit the constraining dimension (give or take about
1-2% of the edge that gets cropped). You can choose which one at the
time of submitting the work either for the whole batch or individually
frame by frame.

The best ones will even let you choose which part of the frame to print
if there is an aspect ratio mismatch between image and paper size.

Provided that there are enough pixels to support the print size
requested most of the decent print systems don't care if the internal
file header says 200ppi & 18" or 600ppi & 6".

If there are too few pixels to support even a 6x4" print then you will
need to interpolate the image up to the minimum size that the printer
will accept.

I downloaded the program and I tried to find the executable file
to give it a try, but I could not. I'd love to figure out how to
work it... I am not a computer wiz, as you may gather. Thanks

Looked at the help system that its developers' site offers?

Martin, the labs would not know which part to crop, unless I
decide. Also, on panoramics I need to make the picture smaller if
I want to see the whole thing. The labs take (for example) the
middle third which appears as a zoomed-in portion. Blinky gave me
the right direction, only if I could figure the program. In case,
are there other programs available that will do what I need?
Thanks again. -gA

Would this do what you want?

You might also want to try JpegCrops (freeware). It provides various
crop sizes and allows you to move the crop mask around each pic to
select the appropriate crop area. It's very easy to use and provides
lossless crops.

gA, what Martin has said is basically the way it works. When you are
taking a shot or editing you are dealing with pixels. When you go to
print you specify a print size, the printing software will figure out
the details.
If your aspect ratio doesn't match the final print dimensions most
services will scale up to fill the print cropping the unprintable
portion. If you don't like their choice you need to crop to the correct
aspect ratio before submission. Some places will let you specify no crop
but you will finish up with edge strips.
Panoramic are a special case, you either need to do it yourself or find
a shop that will accommodate this. I did one at a Walmart using the 8x10
Kodak printer and duplicating the image with some help from the staff so
I got two landscape images if you follow what I mean. They couldn't
duplicate using their standard setup. For this reason I have been
reluctant to play with panorama until I've looked into it more. I think
home printing is probably the answer here.

Most labs resize and crop photos automatically, as you
suggest. You can do better, if you take the time to crop
them individually.
 >> Stay informed about: resizing digital photos 

I have installed/tried all suggested programs and liked their many
features. All of them, however, give the same results which is not
what I am looking for. I am sorry if I wasn't able to express my
requirements clearly!
I don't want to choose where to crop with a 4x6 rectangle. I need
to make my photo in the largest possible size that fits within a
4x6 rectangle, and that could mean shrinking its original size.
When I print a picture my printer asks me if I want the largest
size that fits in the sheet (8.5x11) and still maintain aspect
ratios.. I thought there should be some program capable of doing
this, unless I missed it in the programs suggested here. Please
ask me if I am being unclear. Thanks a million.

If you crop a pic to 4x6 dimensions with a program like JpegCrops,
mentioned earlier, you only eliminate that part of the pic that falls
outside of the crop area. You can then print that pic to virtually
any size you want and it will maintain the 4x6 aspect ratio unless you
decide to change it. If you then want to print to maximum size within
an 8.5x11 sheet, while maintaining aspect ratio, you will get a print
size of approximately 11"x7.3".
Cropping a pic to a 4x6 (2x3) aspect does not restrict you to 4"x6"
prints.

IM does that, as I reported, keeping the original aspect ratio. I haven't
used it in a while, so I didn't volunteer to walk you through the command
for that. Sorry; all I could do was point you to appropriate software.

Thanks again, Jimbok, but I want to do NO CROPPING. I just want to
end up with the largest picture I can get within a 4x6 rectangle.
This means tha the WHOLE existing picture will get bigger or
smaller and the longest side will be either 4" or 6". I like
JpegCrops a lot, but I could not get it to do what I want. Did I
miss something? Thanks all for your patience.
