changing dpi of a photo
Please help! I need to email some photos to a company who are requesting the images need to be a resolution of 72 dpi and be saved at an image size of 1024 x 768 pixels, less than 1MB per
image.
I have no idea how to do this and have no real editing software, only microsoft office and paint. I need to do this today and i would really appreciate any help!
thanks

Use Irfanview:

Open the image in Irfanview. Go to [Image -> resize/resample]. Under "set new size", change the larger number to its target. For example, if the actual size was 4000x2000, change 4000 to 1024. Ensure that "preserve aspect ratio" is selected at the bottom (this makes the other number change automatically) and that the DPI is set to 72, and click "OK.
One of the dimensions is now exact, but the other one is probably not. The company probably doesn't require it to be exact, however. I would send it without adjusting it further.
You can make it exact by adding a border. This is done in [Image -> change canvas size]. If you modified the width, you will add a top/bottom border, and if you modified the height, you will add a left/right border. Get the correct border size by subtracting the target size by the inexact current size and dividing by two. For example, if your image is 1024x681, you need 87px of border (768-681), divided into 44px top and 43px bottom.
A better way of doing this if exact dimensions are required is to change the smaller number in "resize/resample" and then crop to the specified size.
This is difficult to explain in text, so I made you a video:

The crop method is shown first, followed by the border method.
Save by going to [File -> Save as]. Choose the "JPG" type with quality of 80% (in the small right window).

Hi there,
The GIMP is a free editor which is VERY powerful.
The learning curve might be too steep for a same day thing like this where you simply have to get it done and do it right now.
Please read through this:
"Digital image resizing with the GIMP"
[Link](Mouse over link to see full location)
... and if that sounds like something you are easily able to do then download the GIMP and get busy:

... but if it sounds like more than you are willing to learn in an emergency, then check out:
"Batch Picture Resizer 3.2 (resize pictures)"
[Link](Mouse over link to see full location)
... which does what you want very easily along with a great many other things.
It was designed to be simple enough for anyone to use.
I hope you do well.
