WordPress has produced-in image reduction. It automatically creates as much as three images of different sizes, (thumbnail, medium and huge) based on the dimensions in this sub-panel and WordPress also saves the initial image, so you may have a total of four image sizes saved for every image you upload. -

The exception to this is WordPress will not ENLARGE an image to these sizes, for instance if the original image is the same size as the thumbnail dimension you have entered then this image will not be enlarged to the medium or the large size dimensions.
The default THUMBNAIL size is 150 x 150 pixels, this could be changed towards the size you want. The check box beneath the size will crop the THUMBNAIL in your exact size. Un-checking the package will tell WordPress to re-size the image based on the proportional height and width in the original image.
The Medium Size default is 300 by 300 pixels maximum and the large size can measure up to 1024 by 1024 pixels.
These default dimensions are usually adequate for most images.
To get a better idea of how WordPress re-sizes images I'll download the same image twice - once with the CROP BOX checked and another with the CROP BOX un-checked. I'll also use a graphic that is certainly smaller that this LARGE SIZE dimension enter so that we can easily see how WordPress handles the re-sizing.
Through the MEDIA >> ADD NEW sub-panel I am going to add an image which is 640 pixels by 480 pixels. This can be downloaded with the CROP BOX checked so the thumbnail will likely be exactly 150 x 150 pixels and since the image is smaller compared to the 1024 x 1024 pixels for the larger image then WordPress will never obtain that larger image available.
The very first image features a thumbnail size of exactly 150 x 150 pixels considering that the CROP BOX was checked. It provides the medium image available but there is no larger image available because the original size was 640 x WordPress and 480 will not enlarge the photos.
During the 2nd image with the CROP BOX UNCHECKED the thumbnail dimensions are proportional at 150 x 112 pixels and the medium image is the same and still no larger image. Re-sizing in this way does retain a lot of image compared to the CORP where you can lose some the photo.
Even though default settings are generally adequate for the majority of sites you are able to set these dimensions to suite your preferences.
AUTO-EMBED
WordPress will attempt to EMBED media, for instance a videos, into your post once this box is checked. But, for security, this embed feature is simply provided by a listing of of 16 sites which use the oEmbed code. You will get a simple link if WordPress cannot use this embed functions.
MAXIMUM EMBED SIZE will restrict the embedded media to those dimension. If left blank then it will default to the maximum width of your site theme.
UPLOADING FILES lets you control where media is stored in accordance with your WordPress address. The default is set to wp-contents/uploads and it is automatically created whenever you download the initial media.
If you change the above line to another relative path other than the default, the FULL URL PATH TO FILES is used. Enter the full path to the new upload directory if you change the line above.
The final check box will organize your uploads by year and then month. This is automatically performed by WordPress. For instance if you download a file on July 4th 2010 then that image will be in a folder at wp-content/uploads/2010/07.
REMEMBER to save all changes before you exit.
Videos are some of the most powerful and best communication tools around. They supply direct and immediate access to questions and issues and empowers everyone using the knowledge base for growth.
It is my belief that people all go through stages of learning and this a solid foundation will make the difference between sustainable progress along with a constant spinning of the wheels without progress. -
