How can I open multiple images files using ImageMagick's display command? If I enter say display *.png in a directory containing multiple PNG files, only one is displayed. I think I'd prefer them to appear one at a time, but all at once could be useful too.

If you don't specify a delay, imagemagick will load the first image and wait for your input, that is
SPACE - load next image
BACKSPACE - load previous image
If you want to display the images in sequence without interaction, use a delay:
display -delay 50 *.png
To display all of them you could try with
display 'vid:*.png'

If you would like to see all your images at once, you can use montage to group them into a single, temporary image in ImageMagick's MIFF format (which is lossless regardless of whether image has alpha channels or 8/16/32 bit integer/float samples) and tell display to show that:
display <(montage *.png MIFF:-)
The nice thing about this is that montage will lay out your images sensibly according to how many you have:
If you have 3 images:
If you have 4 images:
If you have 8 images:
If you have 9 images:
If you prefer to layout your images yourself, rather than let montage do them automagically, you can specify how many columns (i.e. how many images across the screen) you'd like and it will make as many rows as necessary. So, say you wanted 3 images in each row:
display <(montage *.png -tile 3x MIFF:-)
