How to upload data to program over USB port

I am working on a set of Visual poi (like these and need to upload new pictures to the controllers every now and again. Currently I use a program to convert a picture in to code, paste that code in to an Arduino sketch as a variable and upload the sketch. What other ways are there to upload a new image (preferably without re-uploading the entire sketch)?
