Depending on what hemisphere you're located in, the crescent moon will help you identify either south or north. The Northern Hemisphere is the portion of the earth that's north of the equator, while the Southern Hemisphere is comprised of the area below the equator. All of North America and Europe are in the Northern Hemisphere. The northernmost portion of South America, two-thirds of Africa, and most of Asia are also in the Northern Hemisphere. Australia, Antarctica, the southern third of Africa, approximately 90 percent of South America, and some southern islands off the coast of Asia are in the Southern Hemisphere. This method for finding your direction on only works if the moon is in either the waxing crescent or waning crescent phases, which occur approximately seven days in each calendar month. The crescent phases typically occur at the beginning and end of the month. If you're not sure whether there will be a crescent moon on a given evening, there are a number of online calendars that provide the lunar phases for each month. Just do a search for "moon phases calendar" or "lunar phases calendar." With your gaze fixed firmly on the moon, image a line from the two points of the crescent that tracks all the way down to the bottom of the skyline. If you are in the Northern Hemisphere, the point where the line meets the horizon is roughly south. In the Southern Hemisphere, the point where the line meets the horizon is roughly north. If you are having trouble following the imaginary line down to the horizon, it may help to hold a stick through the tips of the crescent moon as a guide.

summary: Identify whether you're in the Northern or Southern Hemisphere. Locate the crescent moon. Draw an imaginary line from the moon's "horns" to the horizon.

To avoid damaging your hair, set the flat iron to the lowest temperature that will work for your hair. This temperature will depend on the specific qualities of your individual hair. The finer your hair, the lower the setting you should go with. For fine or very damaged hair, use the "low" setting or 250300 degrees. For medium (average) hair, use a mid-range setting or 300350 degrees. Even if you have very thick or coarse hair, you should be able to use a setting below the very highest one. Try 350400 degrees if your flat iron has a temperature gauge. Experiment with settings in the middlehigh range before opting for the very highest one because repeatedly using that amount of heat can be very damaging to your tresses. If you have chemically processed hair, then your heat tolerance will be reduced. The same goes for badly damaged hair. Divide your hair into sections of about a half an inch to two inches. Pin or pull the top part of your hair out of the way and begin with the pieces underneath, near the nape of your neck. The more hair your have, the more sections you will need. Don't try to straighten your hair by randomly grabbing pieces from all over your head; this will take forever and you'll end up with an uneven looking result. Place the hot flat iron on a section of hair and smooth it down from top to bottom. You should start about a half an inch from your scalp in order to maintain some volume. Apply some tension as you go from top to bottom so that you can get the desired straightness. Don't let the straightener linger on any one section of hair for more than 3 or 4 seconds, as doing so will damage and possibly singe the hair. Straighten the various sections of your hair, moving from the sections underneath to the middle sections of your hair. Try not to go over the same section of hair multiple times, as this increases the likelihood of damage to those particular strands of hair. If you have curly hair, however, you will most likely have to go over your hair multiple times to get it to become straight. Once you get to the top section of your head, place the flat iron as close to your scalp as you can, and smooth it through your hair. This will help you to achieve a sleek finish.

summary: Set the right temperature. Section your hair. Begin straightening. Work quickly. Repeat for other sections. Straighten the crown.

There are tons of websites that will let you quickly upload and resize any image file, including JPEG files. Some of them allow you to resize multiple images at once. Search "resize jpeg" to find a bunch of different options. Resizing using a website is most effective while using a computer, not a mobile device. Some of the more popular sites include: picresize.com resizeyourimage.com resizeimage.net Most resizing sites allow you to upload virtually any type of image file. Click the "Choose file," "Upload image," or "Browse" button to find the image file on your computer that you want to resize. If the image you want to resize is on another website, you'll need to download it to your computer first before uploading it to the resizing website. Each website has a different set of controls to adjust the image size. You may be able to click and drag a box, or use sliders to adjust the final size. You may also be able to enter the exact dimensions you want the resized image to be. Making an image larger than the original will result in a noticeably lower-quality picture. Some resizing websites allow you to set a compression level. Higher compression will result in a smaller file size, but will also lead to a decrease in image quality. Look for a quality slider or drop-down menu to change the final quality. Not all resizing websites have quality options. Once you've set your size and quality settings, you can resize and download the image. Click the "Resize" button to load the new image. You'll likely be shown a preview of the changes before the image file is downloaded to your computer. When downloading a resized image, make sure you don't overwrite the original. This will allow you to go back and make changes if you aren't happy with the outcome.
summary: Visit an image resizing website. Upload the JPG file you want to resize. Use the resizing controls to change the size of the image. Select your compression (if available). Download the resized image.
