Description	The Microsoft Document Imaging was originally released with Microsoft Office XP and was included in both Office 2003 and Office 2007 - it has since been discontinued. The format was developed to allow users to scan documents, then OCR (optical character recognition) those documents, view them and if needed annotate them. MDI or MODI as it is otherwise known is an extension of the TIFF file format.

Technical Details	MDI or MODI is a proprietary format which stores scanned documents and can include annotations and/or metadata. MDI files are limited in their nature in that they can only be produced or read by MODI applications or applications that invoke MODI modules. MDI files are an extension of the TIFF file format, however their are a number of differences - with MDI files, three image compression formats are used, a number of individual tag values and a magic number of 0x5045 instead of 0x4D4D.

Category	Image File
Description	PNG pronounced ping is a format for storing bitmapped (raster) images on computers. It was created originally to replace the GIF file format when it was announced that the companies who created the GIF format wanted royalties. PNG uses indexed colors and lossless compression (like a .GIF file), but without those copyright limitations; it cannot be animated like a GIF image.

Technical Details	PNG images are in many ways better than .GIF as they also include an 8-bit transparency channel, which allows the colors in the image to fade from opaque to transparent; GIF images only support fully opaque or fully transparent pixels. PNG supports palettes of 24-bit RGB colors, RGB images or greyscale or RGB images. PNG was intended to be able to transfer images on the Internet, not professional graphics, and so does not support other colour spaces (such as CMYK).
