Hello,
Great module.
I have created an imagefield with two extended fields (caption and credit). One is required and the other is not. Using WYSIWYG 2.1 with TinyMCE.
With WIF, everything works fine. I get the button, I am able to add the image, I can edit the image style properties and select an imagecache preset.
On the WIF window, I can fill in my caption and credit fields, but the information is not being saved. My first hint was the required field complained that it was empty, and I couldn't save the node. After adding a default value to the required field the node would save, but anything I typed in for either of the fields was not being saved, it just contained the default values.
If I turn off WIF, and just use the imagefiled the fields are saved properly.
Thanks
