Hello everyone,
In fact, I have two scripts that work well, the first:
In choosing an image via a form, then resize the image and finally registers with a new name entered by the user.
The second script:
Takes a portion of an image.
What I tried to do:
Modify the second script to allow me to:
Select the image using a form
Take part image
Save the image with a new name entered by the user.
I tried several times to mix the two scripts, but I ff all the time off.
I’m listening to your advice
Thank you
Here are my scripts
