Generally I forward images through mail. Some of my friend ask me to send the jpeg images in 150 dpi(Dots per inch). I dont know how to measure in dpi. Please advice me how to measure?

You can't measure DPI from a picture alone. DPI = dots per inch
DPI is measure of an output DEVICE. For example, your monitor is about 72 dpi, and your printer is 300 or 600 DPI. If you don't change the print resolution, a picture printed at native DPI on the printer will be about 1/4 (72 * 4 = 288) as large. So if you see it on your monitor is 1 inch across, then it'd be like 1/4 inch across on your printer.
HOWEVER, nobody views or prints at native resolution. EVERYBODY that I know scales up to the page, or fits to the screen, or changes the size SOMEHOW, thus completely making DPI meaningless.
Which basically means that your friend's request is meaningless. A picture itself has no DPI information. It just has resolution, period.

Kb and dpi are very much unrelated.
Basically unless you're performing any specific printing tasks, ignore the dpi of an image. People get too caught up in dpi - when the image is intended for on-screen display only, then it becomes largely irrelevant.
Choose a suitable _dimension_ for your image in _pixels_. A suitable size for a photo is probably about 800x600, but you might wish to go larger or smaller depending on your needs.
The Kb size of the file will vary depending on the compressiong format (if any) and how much compression you have done. BMP format is uncompressed, and not recommended. JPG format is compressed, and recommended for this task.
If in doubt - search the internet. There are literally millions of pages on the internet about digital imaging, but they won't come looking for you...

300 Dpi In Kb

kb & Dpi are two diffrent measuring units, dpi for measuring image resolution(sharpness), while kb is used for measuring generally file size. a higher dpi will result in a higher kb. If you check the image "property" in windows or "get info" on a mac it should give you these units. but to measure or edit the image resolution(dpi) you will need an image editing soft wear like photoshop or corel draw. otherwise check the image resolution option on your camera and set to the appropirate resolution- chao:)
