Actually, the DPI is adjusted on the fly in the shops that I am
familiar with. You take a digital image of any dimensions, tell them
on what size to print it, and that's it. Naturally, trying to print
320x240 px image on an A4 sized print will look terrible, but up to
the technical limits of the machine it can be done. Therefore, make
sure that the shop that gives you the disc used a high (at least 300
DPI, and 1200 would not be unreasonable) resolution setting so that
the resultant prints will look decent.

That's very helpful.  I think my local computer repair shop has a scanner, so
I'll try that.
Thanks very much.

You might enquire of the place you take your film for processing whether 
you can specify the PPI of the processed images, in which case I would 
specify a ppi of 300 or more. If you cannot, and you have a scanner, you 
might be able to scan the negative on your scanner, and "develop" which 
would be basically changing to the color balance of the image and 
prepare the images at home.  I have had reasonably good luck scanning 
both positive and negative images made on 35 mm film in a variety of 
media on a flatbed scanner, and processing the film. I scan at 1200 dpi, 
and by printing at the same image 300 dpi, I increase the size of the 
printed image by 4 times.

It depends on the pixel dimensions - if the CD photos are only 360 px
by 504 px ( which is 5"x7" at 72 DPI), you will not get very high
quality prints.  However, I suspect the CD photos are probably much
larger - so you should resize them to 5x7 with software like GIMP and
see what the resulting PPI is...  Wow, does that even make sense?

Let me try again: even though the CD photos are at 72 DPI, they're
probably much larger than 5x7 - if so you can resize them to 5x7 and
end up with a higher PPI.

Most drugstore labs (where I live) can print photos from a SD card or
a USB stick...

There should be no problem in getting a print but I suggest you ask them
first to find out what they require the Gimp image to be saved on.

OK, thanks.  
I just wondered if the CD photos would have the right information - I read
somewhere that the ppi. for photo printing should be about 200, the ppi. for
my CD prints is 72.

Most photo labs nowadays can print photos from digital sources - after all,
film is quickly becoming obsolete.

When I take my 35mm film roll in to my local photo lab for developing, I get a
set of prints on CD.  Can they print a 5 x 7 inch enlargement of one of these
CD prints after I have made some changes with GIMP, or will they only be able
to make a print from the negative (which I can't make changes to)?

Thanks.
