I have a task where I need to be able to replace JPEG images with a fake. The fake need only be roughly the same size as the original. In other words, I do not care if the fake is a single white dot or the blue screen of death. I have never used Image::Magick
nor done anything like this so any help is appreciated.
Update: To clarify, my use of size refers to the file size on disk and not necessarily the dimensions of the image. I do not care about the relationship of dimensions of the fake to the original as long as the size on disk is roughly the same. I have /msg'd the authors of responses about this update in case their advice doesn't apply.
