Load images at proportional size

[Josep]

Thanks Mark,... works fine...

But now I detecting some extrange issue. When Drag from the desktop or the
web page sometime the source image have height and width = 0... I don't know
why, some times drag and drop perfectly and sometime no, and Rev crash!

Code:

on dragDrop
   lock screen
   set the width of me to 210
   set the height of me to 295
   set the threeD of me to true
   set itemdel to "/"
   put the last item of the dragdata into fld lbl_filename
   
   put URL the dragData into me
   put rescale( the formattedwidth of me,the formattedheight of me,the width
of me,the height of me) into myNewSize
   set itemdel to comma
   set the width of me to item 1 of myNewSize 
   set the height of me to item 2 of myNewSize 
   unlock screen
end dragDrop

I set the width and height at the begin to put the original size, so if the
image is rescaled to a small size the next time the image have these size.

Any idea?

Salut,
Josep
