User:Aristeas/Random front-page image

Documentation

This subpage template just creates a complete [[File:...]] element with a (pseudo-)random front-page image for my user page.

The random image technique used here was inspired by Poco a poco’s random sample photo, thank you! (The latter is based in turn on the random image by former user Biopics.) Another idea (for a limited selection) would be to use {{CURRENTDAY}}, delivering numbers 1 to 31.

Argument(s)/Parameter(s)

1. Desired max. width and max. height of the image, specified in the special (maxwidth)x(maxheight)px format, e.g. 640x640px. As usual the Mediawiki software will size the image to whichever value would make it smaller (cf. the documentation).

Caveat

The documentation for the {{Rand}} template clearly states that e.g. {{Rand|33}} delivers integers from the range [0, 33[, i.e. only numbers < 33. This is also how Poco a poco’s random sample photo uses the template. But Biopics’, Hubertl’s and Stepro’s implementations seem to understand the result as a number from [0, n], i.e. including n. And from time to time my implementation (assuming [0, n[) failed and delivered just an empty string for the image name. But this happens even when I assume [0, n], “to be on the save side”, therefore this cannot be the reason of the failure.

There is a new alternative implementation.
