GIF files are very good for saving line diagrams. GIF files have the added advantage that they can save animations. They use a different method to compress data and so do not suffer from blurring.
A JPEG file is solid. These files are generally used as a background type of image. They are good for complex images like photographs; GIF files are very good for saving line diagrams. GIF files have the added advantage that they can save animations. Disadvantage of JPG files is that for simple figures, there is a loss of definition around boundaries; text and clean lines become blurred
What is the difference between and embedded graphic (image) and a linked graphic (image) in a Word or Powerpoint document? Which is the default (the one that happens if you just 'paste it in') and why is this important? How did you find out?
A linked graphic is stored in the source file so that only a representation is shown in the document. If the source file undergoes modification, the information in the document is also updated.
An embedded graphic becomes a part of the document and no longer belongs to the source file so that it does not change when the source file is altered. This is the default setting. This can be seen when a paint file is inserted into Word, then the original paint file is changed and saved once more. The image in the document does not reflect the changes made.
PNG or Portable Network Graphics file, overcomes many of the problems with GIF and JPG files but it does not support animations.
GIF or Graphics Interchange Format use a different method to compress data and so do not suffer from blurring. However, GIF files use only 256 colours and so a high‑resolution image saved as a GIF file may suffer from alterations in hue and some loss of definition.
The BMP file format, sometimes called bitmap or DIB file format (for device-independent bitmap), is an image file format used to store bitmap digital images, especially on Microsoft Windows and OS/2 operating systems. Bitmap images are not supported by any Web browsers or Web coding languages. Therefore, they are not suitable for use as images in a Web application. Bitmap images are best used for their intended purpose, as a system support on a PC Windows-based computer. They should not be used for the placement of a bitmap image when designing for a high-end print production job.
Flickr is a photo sharing website and web services suite, and an online community platform. In addition to being a popular Web site for users to share personal photographs, the service is widely used by bloggers as a photo repository. Its popularity has been fueled by its innovative online community tools that allow photos to be tagged and browsed by folksonomic means (collaborative tagging , social classification, social indexing, social tagging).
