Short Description
Opening an Image
There are several ways to open an image to edit in photoshop { like through photoshop, through a folder or through an image viewer. Note: When opening images, sometimes a message pops up about the embedded profile being a mismatch. ALl this means is that the colour settings of the image are a bit different from the default photoshop settings { as is often the case with digital photos.

Saving an Image
Photoshop can save an image in many different images formats. For photos, you would normally want to save in .jpg. The default format is .psd { this is the photoshop format, which saves layers and other information { it is useful when making big changes to images that you want to be able to alter later. For simple images, therefore, change the format from Photoshop to JPEG. Then name you file and click save (you could keep the same file name and overwrite the original, but better to give it a new name to keep a backup copy).
Next a dialog box appears to control the quality of the image. This is because JPEG files compress the image, and you can choose how much compression to apply. The higher the value, the better the image will appear, but the more space it takes up. The difference will not be very noticeable, except in fine details. As the quality slider is moved, the size of the image is shown in Kb at the bottom of the dialog box. Files above 300Kb will take a noticeable time to send or load { but digitial photos start at around 1000Kb, so this is still an imprvement. It will also give an estimate of how long it would take to download at different connection speeds { the default, as selected by the dropdown box, is 56K modem (old dialup), while boradband is at 1Mbps.
