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:
The final subpath and filename of image required. To obtain this:
Find an image on the Museum website
Right-click on the image and select properties from the context menu, then:
If you are using Internet Explorer, copy the last two groups from the Address property that is displayed
If you are using Firefox, copy the last two groups from the Location property that is displayed (you may need to resize the box to see it in full)
Thus in the following URL, https://images.ltmuseum.co.uk/images/max/iz/i00008iz.jpg, the bold section should be copied. Note this includes the filename extension
The description of the image you want to be displayed.
Example
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.
