-> A big disadvantage to loading an image file as a texture directly, is when that when it loads it, it does so in its compressed format such as *.png* or *.jpg*.  These compression formats are not understood by a Graphics Processing Unit (GPU); they will need to be decompressed into raw bytes as a format the GPU does understand before it can store the data.  Doing this can potentially leave a larger memory footprint for your assets.  You will also need to handle how different compression formats work on the platform you are targeting such as desktops, mobile, and consoles.
