I just downloaded Picasa2 and created a bunch of collages. I sent them
to Costco but when I went to pick them up they were useless. The top
row of 4 pictures (16 total; 4x4) was cut in 1/2, and the bottom row
had been cropped as well. the guy at Costco said digital cameras
require more space at top of each picture to allow for this
"autocropping," and that the effect is exaggerated as you enlarge the
prints (these were 8x10 sheets).

Is there a way to fix this using the current pics that i have? Maybe I
could resize them somehow. I really am new to all of this, so please
type slowly. ;-)
Thanks!

I did search the topic on the Picasa support site, but didn't find this particular issue...

Many thanks!
