The reason a spacer GIF is invisible is so that an HTML developer can create a table cell and fill the background with a specific color that can be viewed through the transparent spacer GIF. For instance, a developer seeking to create a square blue box 500 pixels on a side could use a separate blue 500×500 graphic at the expense of additional ...
GIF animation of an Apollonian sphere packing with transparent background. Transparency in computer graphics is possible in a number of file formats.The term "transparency" is used in various ways by different people, but at its simplest there is "full transparency" i.e. something that is completely invisible.
PNG is a raster graphics format. PNG has advantages over SVG including smaller filesize (due to less-than-optimal server-side SVG-to-raster conversion), more widely supported and often easier and faster to make simple changes to things such as borders.

Border border. Put a small border around the image. Location right, left, center or none. Determine the horizontal placement of the image on the page. This defaults to right for thumbnails and framed images. Alignment baseline, middle, sub, super, text-top, text-bottom, top, or bottom. Vertically align the image with respect to adjacent text.
GIF was one of the first two image formats commonly used on Web sites, the other being the black-and-white XBM. [5] In September 1995 Netscape Navigator 2.0 added the ability for animated GIFs to loop. While GIF was developed by CompuServe, it used the Lempel–Ziv–Welch (LZW) lossless data compression algorithm patented by Unisys in 1985.
Wiggle stereoscopy is an example of stereoscopy in which left and right images of a stereogram are animated. This technique is also called wiggle 3-D, wobble 3-D, wigglegram, or sometimes Piku-Piku (Japanese for "twitching"). [1] The sense of depth from such images is due to parallax and to changes to the occlusion of background objects. In ...
Where borders are desired, they should be added with wikimarkup or code. Any text from the border should instead be in the caption. If the border has author or license information, add it to the file's EXIF information. To crop the image yourself, use the CropTool. If cropping a JPEG, consider using a lossless cropping tool such as jpegtran.
