Example photo page layout

The following creates a 10x10in page with four pictures on it in a nice grid. You can change the size of the page and the image sizes will adjust as well. The images can be scaled, cropped, and moved behind the display frame. There is probably easier ways to do this, but I needed a way that would work with our web service. This captured all the parts we needed in a generic way.

% output=pdftex
\definepapersize[imb][width=10in,height=10in]
\setuppapersize[imb][imb]
\setuppagenumbering[alternative=doublesided, location=]
\setuplayout
  [backspace=1.25in,
  cutspace=1.0in,
  width=fit,
  topspace=.25in,
  bottomspace=.25in,
  header=1.0in,
  footer=1.0in,
  height=fit]

\newdimen\spacebetween \spacebetween = 0.5in
\newdimen\imagewidth   \imagewidth   = 6in
\newdimen\imageheight  \imageheight  = 4.5in

%my cow.jpg image was 6in x 4.5in @300dpi
\useexternalfigure[imagea][cow.jpg][width=\imagewidth,height=\imageheight,frame=off]
\useexternalfigure[imageb][cow.jpg][width=\imagewidth,height=\imageheight,frame=off]
\useexternalfigure[imagec][cow.jpg][width=\imagewidth,height=\imageheight,frame=off]
\useexternalfigure[imaged][cow.jpg][width=\imagewidth,height=\imageheight,frame=off]
