this works for me:
on mouseUp
answer file ""
if the result = "" then
set the data of me to URL ("binfile:" & it)
put the Data of me into image 1
end if
end mouseUp

So then something like this attached to a button should work? It
doesn't seem to. I select a JPEG image file (I tried several
different ones).
on mouseUp
answer file "Select an image file:" as sheet
put it into x
if there is a file x then
open file x
read from file x until EOF
put it into y
close file x
set the text of image "Logo" to y
end if
end mouseUp
If I set the filename of image "Logo" to x, then the image appears,
but I need to be able to take the data from a database field (and to
take image data from a file and store it in the field), so I need
functionality similar to the above.
What am I missing here?

Hi Frank,
How can I take binary image data stored in a variable (obtained
programmatically,
usually from a database query) and display it in an image field
without first storing
it to a file? I can't seem to find any information on this.
I tried this, but it doesn't seem to work:
set the fileName of image "Logo" to empty
set the imageData of image "Logo" to an_obtained_value
when using "the imagedata" you have to make sure that the "target"
image has EXACTLY
the same dimensions as the "source" image, or you might expereince
ugly results...
But you can:
...
put a_var_with_binary_data into img 1
...
and it will resize to the correct dimensions :-)
It's also important to know that imageData and the content of an
image (its text property) aren't in the same format.
The imageData is an invariant format that provides the RGB data for
each pixel. The text of the image is the image's data in whatever
format - PNG, GIF, JPEG, or whatever format the image is encoded in.
Normally, if you get the data from some other source, it will be in
PNG, GIF, etc., so you'll use a statement like
put myImageData into image "My Image"
Only if you're modifying the image data yourself do you use the
imageData, usually.
