Deprecated: The purpose previously served by very high-resolution file downloads is now served on Commons by tile sets. See Category:Tile sets. This page is retained for historical purposes only and the HTTP and Torrent links below are no longer operational.
Some files on Wikimedia Commons are uploaded at reduced resolution and/or quality due to technical limitations, such as the 100 MB upload limit, or limitations on the maximum height and width of a JPEG file. Some of these files can be downloaded at full, original resolution and quality from third party providers, optionally using a BitTorrent client. These are listed here with links to third party download pages. These archives should not contain any executable files and so should be safe from malware.
Note that some images below may be too large to load into memory on ordinary PCs. These are represented using sets of image tiles, and special software may be required to view or process them. These are marked Tiles only in the table below. See Image tiles format below for details. These images should use the {{Tile set available}} template on their file description page.
Images marked "Tiles only" are represented by a large collection of fixed-size JPEG tiles (typically 256x256 or 512x512). The filenames have the form "x##-y##.jpg", where the first number is the column and the second is the row, both zero-based. The file info.xml gives the number of tile rows and columns and the number of empty pixels at the right and bottom edges (these should be discarded/ignored during viewing or machine processing). For images from Prado in Google Earth, the rows count from the bottom of the image (y0 is the bottom row), whereas for images from the Google Art Project, rows count from the top (y0 is the top row).
Viewing or processing an image represented in this format requires special software (which does not currently exist but would be simple to implement). Even if the tiles were assembled into a single TIFF image, which is possible, merely loading it in a standard image editor like Photoshop would require far more RAM than most PCs have. Moreover, the JPEG file format does not support images of such high resolution due to limitations on width and height.
A complete tile pyramid can be constructed by combining and downscaling each group of four adjacent tiles to form the next pyramid level down, then repeating this until a single tile is reached. Such tile pyramids are routinely used by viewing software for very large images, which load the tiles in view on-demand, and use the different levels to support zoom functionality. It is also possible to create software which crops out a portion of the image (a detail) and saves it as a JPEG at maximum resolution. If you create software like this, please consider publishing it under an open source license so that others can benefit from it. There may also be other unanticipated uses for this data.
