Is there a way to get more than 6MB per pic uploaded or a way to change the size of the picture. I do not want to get new pictures as these have already been retouched. Thanks,

There is no need to retake your photos. You will need to resize them to fit the parameters laid out as to the max allowed for listing photos. The new Matrix system has an image resizer for Windows users. Since I use a Mac I cannot attest to how easy this is to use. Rather than go into detail on how to resize a photo - I would encourage you to google it or watch a youtube video to see how it is done. It is pretty easy once you know how. If you hire a photographer to do your photos they will often give you photos in both a large and small (postable) file sizes.
