The purpose of this template is to access images on the London Transport Museum Photographic Collection website at https://www.ltmuseum.co.uk/collections/collections-online/photographs. This site contains an extensive collection of images of London and its public transport (buses, trams, trolleybuses and tube trains) from the 19th century to the current day. It is therefore a useful resource for anyone preparing articles on any of these topics.
The template takes the format: {{LTM collection|1|2}} which expands to: [https://images.ltmuseum.co.uk/images/max/{{{1}}} {{{2}}}]
Currently the two parameters are:
In the following example the last two groups of the URL are iz/i00008iz.jpg and the description to be displayed in the article is Tube train at Aldwych station, 1958.
Thus: {{LTM collection|iz/i00008iz.jpg|Tube train at Aldwych station, 1958}}
Produces: Tube train at Aldwych station, 1958
