Since this would be an export , why isn’t anyone mentioning the dpi? If I export at 3200 pixels on the long side can’t I also set the dpi? And if I make it with a higher dpi won’t it be a bigger jpg with more quality up to the limit of the way it’s viewed.
Are there any non-proportional resizing software out there so I PRINT a 4x6 aspect digital image to some other aspect WITHOUT CROPPING? On1 resize used to but doesn’t now. Topaz Gigapixel doesn’t. I’ve heard PhotoShop does?

No one mentioned DPI because it's a nonsense value for pixel-based digital images. Even the competition knew to not mention DPI in their submission instructions.

DPI has no bearing on digital display. It only matters for printing. On screen a pixel is a pixel. Even that 3000x2000 pixel image is too large to fit on a display showing at 1:1. It is resized again by the software that’s displaying it.

Did you see PRINT IN ALL CAPS.

You can yell DPI for ever hour of the rest of your life, it still won't make it relevant to pixel-based images ....

It sure has hell matters when I print.
Does it? Does it really? What makes you think that? How may dots are there in a pixel? How many pixels in a dot?

First off getting a Jpeg file size over 15MB would be hard to do unless you were shooting with a 50MP full frame sensor. RAW files with edits sure.
Linda's question about editing software is important to answer further. That being said 25MB is a huge jpeg file. Your image is probably way under that and you should be able to determine that by looking at the image properties.

I shoot with a 22mp camera and jpegs are around 23MB

Most programs will allow you to reduce the file size. For instance - in Lightroom I can export images, adjusting file size, by; Width & Hight, Dimentions (Pixels, inches, Centimeters), Long edge or short edge (Pixels, inches, Centimeters), Megapixels and percentages.
This should not be hard to figure out. DPI (PPI) only comes into play when your Printing:
"DPI stands for Dots Per Inch which technically means printer dots per inch. Today it is a term often misused, usually to mean PPI, which stands for Pixels Per Inch. So when someone says they want a photo that is 300 dpi they really mean that they want 300 ppi.
PPI is simple arithmetic, it is the digital photo's pixels dimensions divided into the paper size to be printed. A digital photo itself has no PPI, the PPI only occurs when it is printed."

Final word on DPI since many of the UHH'ers still don't get it. The following is a clip from: http://www.rideau-info.com/photos/whatisdpi.html
DPI/PPI Setting in a Digital Photo
The original DPI term, as used with a digital photo, goes way back to the days when a digital image was printed to a printer using a 1 to 1 ratio (1 pixel = 1 printer dot). This has not been the case for several decades and today that legacy term is only directly applicable to scanning, where one scanning "dot" equals 1 pixel (and even then it's not correct since a scanner is really scanning PPI - but most scanning software still uses the term DPI). It's also not applicable to modern printers since they use a blended dot and they completely remap your image to convert it into print.
But you will still find a DPI or PPI setting within most photo software. This is where the confusion generally starts and I've detailed it ad nauseam on my Myth of DPI page. This setting in a digital photo is simply a conversion calculator, showing you what the printed size will be at any given PPI, or, given a specific printed size, what the PPI will be. It is a useful setting for graphic artists who are used to working on virtual paper and can be a useful setting to you simply to know what your print resolution might be for different paper sizes (rather than having to use a calculator). But, it has nothing to do with the digital resolution of the photo, those are its pixel dimensions.
This is also a very dangerous setting in most photo software since it can be used to re-size the photo which can lead to much grief and misery if not done properly. Please read the Change Size section of this website before you even consider touching the number in this section of your photo software.

Sure you mentioned PRINT in your second paragraph, when talking about your own prints, but in the first paragraph you asked why nobody mentioned DPI in their responses to the OP, and that had nothing to do with printing.

Are sending those raw files? I didn’t think so. How big are the jpegs?

Not related but what is the circle upper left middle in the picture???? Kind of looks like a water mark.
