    Look up a common image source and figure out how the bits are formatted. I would suggest using either .BMP http://en.wikipedia.org/wiki/bmp_file_format or

    .PPM formats as they are very simplistic

    http://netpbm.sourceforge.net/doc/ppm.html

    Then write a conversion program that arranges the bits how you like.

    The PPM format you may be able to read directly.

    Inkscape is a good GPL program to try to convert from one image format to another.

    Python also has image reading routines that can be used to convert image formats. import the image module and you can read several different file formats.

    Quartus won't be able to do that for you, you'll need an external software or a script you make yourself. You can either convert your image to a .mif or .hex text file to use it as initialization contents for a RAM or ROM block generated from the Megawizard, or convert it to a table in a HDL file, either Verilog or VHDL.
