Try sending your picture to yourself via email as a medium size attachment. Then save the smaller version and try to attach it. That has worked for me before.
If we knew the pattern it would be easier to make suggestions. My favorite thing is to applique something over it. It could be a large flower, or a paint splat spot. A vase with flowers. A special poem. Or, you can use the same original fabric, wash it, and then cut it with enough to have a 1/4 inch seam to turn under and applique it over the parts that are messed up. Any of this will work. I am sure others will have more suggestions.
