Photography

I have taken photographs in JPEG format could anyone tell me if i can convert them to high resolution.

they'll already be in some sort of resolution - your camera is probably set to high, middle or low, so check to see which it is.

You can 'interpolate' (falsely add extra pixels) to your original files using an image editing programme such as Photoshop.

You can not retrospectively add information the camera did not gather at the time, but as mentioned, there is software that can process your picture files and guess what a pixel in between 2 you have information on would have been, had you taken the picture at a higher resolution. If you follow :-)

JPG format creates smaller files than might otherwise be the case, by leaving out information it believes your eye will not miss. The amount of information discarded is settable, although there is a knock on effect on file size, and on picture quality. But ultimately the control you have is down to what your camera allows you.

Just to add: always set your camera's resolution to the maximum available (invest in a larger capacity memory card if your max. resolution setting drastically reduces the number of images your camera can store) as you can always reduce/throw away resolution but, as Old_Geezer says, cannot so easily increase/add it.
