I have some photos that were taken when I had a 4 mega pixel camera and I want to have them printed as big as possible without them being grainy. Is there something is Photoshop or anything that I can do to multiply the pixels in an already existing photo? I appreciate anyone's ideas!

Yes there is a way to increase the image size and it is called interpolation however blurring and digital artifacting are the negative side effects. On the other hand if you don't make huge leaps in enlargements, the effects aren't readily apparent. You may want to experiment, to increase an images size in Photoshop go to edit > image size. Usually after you make an enlargement in photoshop you will most likely have to run the image through a unsharp mask filter, though I personally don't use this method to increase the sharpness. However, by increasing the sharpness you will have more visible grain or noise. There are of course specialized image enlargement software titles that utilize better or at least more versatile interpolation algorithms one of which I included below.

Increase Pixels In A Picture

I presume you mean the 10mp D40x; the D40 tops out at 6mp. The request makes no sense. Even at 5.6 mp, that's way larger than any screen size for a web shopping cart. So, I'm thinking that your web designers may not be talking about the image size itself, but rather they're looking at the file tag for the file, which might be set at 72 dpi. If you have Photoshop (and you should if you don't), check to see what the image resolution is set for. If it's lower than 300 dpi, all you need to do is change the dpi to a higher number, which changes the file tag and then save the image. Alternatively, if they want more megapixels, you can try to increase the size via interpolation using photoshop, which, while it won't be the same quality as shooting at 10mp natively, will be very close enough that the web designers won't be able to tell. Frankly a 5.6mp shot from an SLR is more than enough to make a great 8x10" print, so I have to wonder what the designers really want. First though, I suggest talking to the designers and clarifying what they mean by wanting you to "increase the rez" That could mean just about anything from, you didn't get enough close-ups to your photos are out of focus to they want a file tagged at 300 dpi. Once you know what they want, you can decide the best method to provide it to them. BTW, your highest quality is to shoot RAW files and then convert them to jpegs via computer. If needed, you can shoot RAW + simultaneous jpeg. If you shoot jpeg only, you're better off keeping the full-size resolution and increasing the compression for the jpeg (i.e. 10mp jpeg, normal compression) than to reduce the size of the jpeg itself (i.e. 5mp, fine quality). Hope this clarifies things for you a bit. I think you need to talk to the web designers.

4 isn't the max but you still can't increase the pixels

no. each pixel is whatever color that the camera recorded. you cant create more details after the fact...however there are programs that randomly generate pixels, but its not always good.

Adding pixels will decrease the quality as it gets larger. You can not create what is not there.
