well, PICT: PICT files can be uncompressed or compressed using the JPEG compression described above. Most PICT files that are saved uncompressed are still smaller than several other image formats because of the PICT format's internal compression algorithm. It is best suited for images with large areas of the same color, which can be saved most efficiently. Like JPEG images, PICT files cannot include layers, but can include some path information from vector images. Since PICT was initially a Macintosh format, some Windows programs cannot open PICT files.
TIFF- ( Tagged Image File Format) This file format has not been updated since 1992 and is now owned by Adobe. It can store an image and data (tag) in the one file. TIFF also stores files with virtually no compression and therefore is good for storing images that need to be edited and resaved without suffering a compression loss. This file is commonly used for scanning, faxing, word processing, and so on. It is no longer a common file format to use with your digital photos as a jpeg is great quality and takes up less space.
JPG, JPEG - (Joint Photographic Experts Group) Jpeg format is used for colour photographs, or any pictures with many blends or gradients. It is not good with sharp edges and tends to blur them a bit. This format became popular with the invention of the digital camera. Most, if not all, digital cameras download photos to your computer as a Jpeg file. Obviously the digital camera manufacturers see the value in high quality images that ultimately take up less space.
