Just came across this…
A very quick way to generate a bunch of image sizes for testing: http://dummyimage.com/
(I wouldn’t hotlink to his server in your themes without asking but he provides the source download)
I like the idea. It’s a time saver when you want to create a place holder
and thank you cudazi for sharing this
I just installed it locally and it ran nicely… AFTER I remembered to start WAMP before attempting to use it of course.
