You should have a set of baseline images that you know the source of. Things you made in Photoshop using your digital camera, that you can validate the color space and dimensions of.
I would also collect random images from around the web from various sources such as a Google Image search, Flickr, Picasa and such. This will give you the random element that tends to come in from user generated content... The more random the better, in fact using a random URL generator and grabbing the first image would be a good idea. Here are some common things I've seen that CAN break image processing: - Wrong color space: ie CMYK - Bad formatting in the image exif data - embedded color profiles =] On Wed, Aug 18, 2010 at 12:46 PM, Pete Freitag <p...@foundeo.com> wrote: > > Hi Dominic, > > I think when it comes to image files you will want to have some local > test files, because you can potentially run into issues with the way > different image editors save files.
