In Photoshop, navigate to the Image menu, then click Image Size... You can change the amount of pixels in the Pixel Dimensions section.
If you don't have Photoshop you can download the XnView image viewer for free and use that to resize it. Open the image in XnView, click on Image then Resize. You can change the resolution in the Screen Size section. After you change the size you will need to save the image from the file menu to save the changes when you close XnView.

Compute the Size of 800x600 image at 240 pixels per inch?
If the image is 800 pixels by 600 pixels at 240 pixels per inch, then the image size is (800 / 240) by (600 / 240) or 31/3 by 21/2 inches.
What is the relationship between image resolution and size?
The image resolution of a picture is broken into pixels. The amount of pixels in the picture depends on the size of the print. There are approximately 100 pixels per inch in a picture.
How is image resolution expressed?
Image resolution is usually expressed by giving the dimensions of the image in pixels. The size of an image that is 640 pixels wide and 480 pixels tall would be expressed as 640x480. 640x480 is read as "six forty by four eighty".
What is the process of enlarging or reducing an image without changing the number of pixels in the image called?
ResizingBy: UnaxyIf you are changing the size it's called scaling or 'resizing,' if you are changing the size while clipping out unneeded outer parts, it's called 'cropping.'
How does the file size change if the total number of pixels of an image is doubled?
The file size doubles.
Compute the size of an 640*680 image at 240 pixels per inch?
The size of the image is 2.67 inches x 2.83 inches (width x height) when printed at 240 pixels per inch.
How resolution and colour depth affect file size and image quality?
Changing the image resolution will affect the file size of the image and the quality of the image. Image resolution is measure in DPI, which is Dots Per Inch, this means that if you increase the resolution then the DPI will increase and the quality of the image will get better as a result as there are more pixels that make up the image, so the image will be more distinct and sharper. When the image resolution is increased the image has more pixels, this is the exact opposite to the compression techniques, this means that the file will get a lot bigger as the number of pixels increases. Decreasing the resolution, however, will make the image quality lower but will reduce the file size.
Is there any place you can go to get an image measured in pixel dimensions?
most image editing software will be able to tell you the image size in pixels, or if you are running a later version of windows and right click on an image, go to properties, and then click on the details tab, it will have the dimensions in pixels
Is there much difference between 160x240 pixels and 240x400 pixels?
The only differences are the number of pixels involved, and the shape of the rectangle they form. 160x240 pixels is a rectangle of 38,400 total pixels. 240x400 pixels is a rectangle of 96,400 total pixel's. Note that because the two rectangles are not the same shape, if you are trying to re size an image or change the size of a photo you are about to take, the two sizes will not give you the same picture shape. To achieve a larger or smaller image without altering the shape, multiply or divide the two numbers on either side of the "x" by a common number. For example, multiplying the numbers by two would result in an image twice the original's size, and dividing them by 2 (or multiplying by 0.5) would result in an image half of the original's size.
What is pixel pitch?
Pixel Pitch is the measurement of the smallest bit of data in a video image. The smaller the size of the pixels in an image, the greater the resolution.
What is pixels are used as a measurement of?
Pixels is a measure of the image size, each pixel is a dot. This has nothing to do with quality, more megapixels DOES NOT mean better quality pictures. A 10 megapixel camera has 10 million pixels (or dots) per image.
How many pixels to an inch?
There Is No One Answer to Pixels per Inch, However, pixels are different sizes on different displays, so the answer is 58.74 pixels per inch on a 75-inch 4K television, for example, but 440.58 pixels per inch on a 5"-inch full HD smartphone screen.
