Not true that images are not harmful... I work for an MoD contractor working in Defence Information and Intelligence (cyber security).
PC based images are complex formats and contain meta data and other parts that are not directly visible when painted onto the display — it is possible to conceal "stuff" within without affecting how the image is displayed on the screen , even when hyperlinked. Venomous data can reside within the image that exploits "back doors" in poor quality image rendering programs - including doors like stacks, buffers, data segment larger than the stated image format type and exception handlers and alike. With skill, a virus writer :b can utilise these flaws to infect your machine when you open the image with a certain program. Granted this wont work just displaying the image as Mickvp said, but if one were to click on the image and open it in a certain app, then Bang!! you're infected.
Just thought I'd clear that up for the Admins
