Kyle:
I have done this, but it involves a few things. First, I use an image
control on my form that will display the picture. Second, I do NOT store the
images in my database, I store the images in some folder on my computer and
only store the path to the image file in my database. Third, I use API calls
to do the File/Search method from some button's click event. Fourth, once I
get the path to the image via the API call, I set the .ImagePath property of
my image control.
With that said, here is some code that I use in my button click even that
will do the Find for the file and display it in the control. If I missed
anything, you may have to search the Web for the API calls needed to do the
File Search method.

Ok on my form i have a field for a picture, my data table is all set up to
add the picture and what i would like is to be able to click on the field
where the picture will go and have the file pathway window show up. I think i
have to build an event with a mouse click but im not sure what code to input.
Also i cant figure out how to get the picuter to accutly show up in the box
i have created. for the field, in propterties and on the data tab i have
=[Pictures]![Photograph] the first 'pictures' is the data table with the
pictures in it. i have entered a few pics via the data table which has a
working hyperlink to the pic but what else do i need to do to make it show up
in the form.
Thanks!!!
