It is suggested that visuals of graphics are retained for about three months. This allows for the fact that large packages may be released up to two months in advance, and news stories sometimes rumble over quite a period of time. It is not necessary to keep graphics for longer as access to the archive is available online.

The storage required to keep files for this length of time is insignificant compared to the space needed for pictures because graphics are relatively scarce and the files sent are smaller than those of pictures.

To calculate how much storage space is required one has to make some assumptions. If one assumes: then for visuals for each language requested, the storage required would be about 13 x 30 x 300KB = 120MB
