Blueprint placeholders is a collection of nearly 750 placeholder images, optimized for the Blueprint CSS grid, useful for quickly prototyping designs.
Most of the images in this collection use the familiar Blueprint class names: span-1 to span-24 (e.g. span-4.gif) and are overlaid with the image's dimensions which makes them quick and easy to use. There are a number of ready-made sets:
Images in both 4:3 (standard) and 16:9 (widescreen) ratios, spanning 1 to 24 columns.
All images are rounded up or down to the nearest pixel.
Images in both 4:3 (standard) and 16:9 (widescreen) ratios, optimized for the grid.
All images are rounded up or down to the nearest line-height value to fit the grid.
If rectangles aren't your thing then how about squares?
There are two sets: one fits the columns, the other fits the line-height (rows).
As well as the basic images above you also get images for specific purposes:
All images were created using the excellent http://placehold.it/ by Brent and Russell.
The grid option enables you to use any combination of column (1 to 24) and row (1 to 25) to keep your design true to the Blueprint grid.
The format for grid-based images is simple:
/grid/span-[number of columns]-rows-[number of rows].gif1

The above are:
/grid/span-11-rows-15.gif/grid/span-5-rows-4.gif/grid/span-3-rows-10.gif/grid/span-2-rows-3.gif/grid/span-2-rows-6.gifThe ratio set gives you either 4:3 (standard ratio) or 16:9 (widescreen ratio) images. These images are designed to perfectly fit the columns of the Blueprint grid. You will notice that the images do not fit the rows of the grid.
The format for ratio-based images is simple:
/ratio/span-[number of columns].gif/ratio/span-[number of columns]-wide.gif1
