What I want to do is have a file browser appear in a popup and be able to select the file/image you want and then to have that file/image id/handle fill the a field within a form on another page.
What I want to do is similar to CKFinder, however, i need it for personal use and potentially commercial use but I can't (well i'm unwilling) to pay for something that I could potentially create myself.
That too Been a while since I've used a traditional popup
For popups you don't use parent but window.opener
The popup can communicate with the opening page by referencing parent. E.G.
parent.formName.formElement.value = '1234'
Is that what you're looking for?
