setting filename of image objects takes a l-o-n-g time

[Barry Levine]

Consider the following script:

  repeat with i = 1 to 21
     set the filename of image ID i to "resources/" & item i of 
allThePieces & ".jpg"
     set the name of image ID i to item i of allThePieces
   end repeat

Setting the filename takes about 37 ticks (one half second!) per 
iteration (or over 13 seconds total!). Setting the name of the image 
object itself takes less than 1 tick.

Looks like I am either doing this wrong or Rev has a problem. BTW, this 
was also the situation with v1.1.1

Current setup: Dual-867 G4 / 512MB RAM / OSX 10.2.6 / Rev2.0RC1

Suggestions always welcome.
