Assume you have:

./pict/
    6-13-04/
    6-14-04/
    ....

Try:

---
#!/bin/ksh

dest=/tmp/pict_all
[ -d $dest ] || mkdir $dest

# assume you are sitting in "pict"
# change to "jpg" if needed
find . -name "*.JPG" -print |
while read f
do
    new=$(echo $f | sed -e 's=^\./==' -e 's=/=_=g')
    cp $f $dest/$new
done
---

This is untested!!!  Try changing the "cp" to "echo cp" to see that it's 
doing the right thing before you run it for real (without the echo).  
Feel free to change the "cp" to "mv".

HTH,
