i have a small problem i don't see a simple solution for.
Maybe someone here has one.
I want to display JPGs from file, so i make a
put URL ("binfile:" & my_file) into image "im_1"
This is working OK.
But when the JPG in the filepath my_file is faulty (broken download
The above line displays an empty image "im_1".
I now want to identify these faulty images.
I tried the following with no result:
if the imagedata of image "im_1" is not empty then ...
if image "im_1" is not empty then ...
if the length of image "im_1" > 0 then ...
Has anyone an idea how to identify an "empty" image?
(its not realy empty but nothing is displayed)
