For most types of graphics file formats currently available the answer is "no". A virus (or
worm, Trojan horse, and so forth) is fundamentally a collection of code (that is, a program) that
contains instructions which are executed by a CPU. Most graphics files, however, contain only
static data and no executable code. The code that reads, writes, and displays graphics data is
found in translation and display programs and not in the graphics files themselves. If reading or
writing a graphics file caused a system malfunction is it most likely the fault of the program
reading the file and not of the graphics file data itself.
