Event he large cameras usually have the option, in the PC software to save the pic as a 'best for web', or at least 25% setting. My 3.2mp which takes about a 1.2 meg file in it's best resolution, can easilly have the file saved down to 50k using 'best for web' settings.. etc. See if yuor software has that option.
In any case, That didn't look like the op platform that my 1920 had.. i wonder if they had a few different op platdorm options?
