Some good answers here already; but some rely on hiding errors which is not a good idea (that assumes mv will only error because of a condition that is expected - what about all the other reaons mv might error?).

Moreover, it can be done a little shorter and should be better quoted:

for file in *; do
    printf -vsequenceImage 'image_%03d.jpg' "$((++i))"
    [[ -e $sequenceImage ]] || \
        mv "$file" "$sequenceImage"
done

Also note that you shouldn't capitalize your variables in bash scripts.
