Photoshop>file>save for web
change image size to 640 x 480 pixels, apply; then select jpeg quality to give you the needed file size; then save.

You can also bring it to a commercial service (Fuji spring to mind) that can print out almost any size. They use photographic process, ie, the electronically photograph your pic, and then develop it/print. I've seen some amazing results.
This not totally related to the above. How do I reduce the size of my image to post it without losing image quality for viewing? 150k or 800 max one side. It seems to be a trial and error method in photoshop and in digital photo pro. Any help will be appreciated.

No tricks to that one ;-) it all depends on how big you print it.
if you have an image 3072x2048 and you print it without cropping at 300 ppi (pixels per inch) then the image would be:
3072 / 300 = 10.24 inches
2048 / 300 = 6.82 inches
if you print it at 30x20 inches then you would wind up with a ppi of:
3072 / 30 = 102.4 ppi
2048 / 20 = 102.4 ppiRemember that ppi, or pixels per inch is not the same thing as dpi, or dots per inch when it comes to inkjet printers. Each pixel of the image printed on an inkjet printer is made of multiple "dots". The terms ppi and dpi are used quite often interchangeably, but for accuracy when dealing with math, I like to separate their meanings.
...Now I have a question for Mr. Stephens if he's still with this thread. What does a fellow with a D70 or any decent 6mp camera do with a publication that demands that you submit an 11x17 inch spread at 300dpi. How can this poor guy (or anyone short of a full frame camera) do that without interpolating up to an excess and resulting in loss of sharpness and "blockiness"?ThanksBob
I bet you already have a clue to your own answer. The short answer is that interpolation, by itself, does not increase actual detail. If the requirements are "11x17 inch spread at 300dpi", then you need an imager capable of that native resolution.
Of course, depending on the publication and the nature of "your" image, the publishers might be more flexible for true, once-in-a-lifetime type images.
If a full two-page spread in one of the leading publications is your goal, I suggest you need to invest in equipment that publication deems worthy of the process.
The least expensive method is film based and then drum scan, at least from an initial purchase perspective. Ultimately processing and scanning fees will drive you broke, but there is something truly special about a good large format view camera, a great set of lenses and transparency film.
Fuji Frontier systems use an optical printing system which emulates ~600dpi quality, from a 300dpi file.
I understand what Bob was asking about the 300 dpi for submission to publications. Most of the magazines that've printed my pictures have asked for 300 dpi files.
I think it's silly to rezz up to 300 dpi creating a 30 MB file which I then have to resize down and send.
So, what's the "easier" way to get a 300 dpi file sent to them? Most e-mails won't take attachments over 10MB.
