Hi.
Do you really want to use a field for this, as opposed to a button? Not that it matters, I was just wondering. Anyway, in either a button or a locked field, place this in the script (pseudo):
Code: Select all
on mouseUp tButton
if tButton = "1" then
import paint from file "yourFilePathHere"
set the rect of last image to "20,20,200,200" --just an example
set the lockLoc of last image to "true"
set the loc of last image to whereverYouWish
else if tButton = 3 then
--another file path to an image
end mouseUp
Setting the lockLoc is important. Try not doing so and see what happens. A cool thing here is the use of the "last" keyword. This comes in handy in just this sort of case. You can:
Code: Select all
set the name of last img to "whatever"
If you need more help with any of the above, write back...

Hi,
You may use imagesource
Code: Select all
set the imageSource of character to {imageID | imageName | imageURL |empty}
Best regards

Thanks for helping. I get error code in line 9: missing 'end if' command.

That is why I mentioned "(pseudo)".
This was not a working handler.
Do you need a working sample handler to get going? Since you are "live" with me right now, I can do that for you.

Anyway, here (and this is pseudo again, since things like "yourFilePathHere" are placeholders, not real LiveCode words):
Code: Select all
on mouseUp tButton
if tButton = "1" then
import paint from file "yourFilePathHere"
set the rect of last image to "20,20,200,200" --just an example
set the lockLoc of last image to "true"
set the loc of last image to whereverYouWish
else if tButton = 3 then
import paint from file "yourOTHERFilePathHere"
set the rect of last image to "20,200,200,400" --just another example
set the lockLoc of last image to "true"
set the loc of last image to whereverELSEYouWish
end if
end mouseUp

An interesting idea, especially since the OP mentioned using a field. But won't this get a bit crowded in a single field, applying imageSources to various chars? I got the feeling that several images were intended to be loaded.

Hi SEAL29,
welcome to the forum!
If you want to select an image from your HD, do like this:
Code: Select all
on mouseup
## Show the system OPEN dialog:
answer file "Please select an image file." with type "Images|jpg,jpeg,gif,png|"
## IT contains the path of the selected image file
put it into tFile
## Check if user clicked CANCEL
if the result = "Cancel" then
## No need to conttinue in this case!
exit mouseup
end if
## Now continue like Craig suggested:
## Import that image file into your stack:
import paint from file tFile
set the rect of last image to "20,20,200,200" --just an example
## ...
end mouseup
Best

Hi Craig,
Yes, you're probabily right to invite SEAL29 to reconsidere use a fld to display image.

I should have guessed that you needed help with securing the pathname. This will all come as you work through stuff and solve problems.
Don't be shy. Ask for details.

It is possible to store only the image reference and not the whole picture (with script). Since there are many images will have a large file size over time?

If you plan on large numbers of images, I would store them in an external file and load as required. This keeps your stack lean. Loading an image takes no time, and external files do not care how large they are. In this way, you only need LC to present the particular image you need.
If you are making a standalone, you must include that file in the standalone settings.
