[TYPO3-project-formidable] Image Preview in Editform

[Markus Lange]

Hi Pablo

thank you for your anwser!

Unfortunaltely this did not worked for me.

To delete a pic in editmode i figured out the code below and it works 
pretty well.
i have to update the record and repaint the form
they might be better ways (but its first time i use formidable and iam 
quite impressed!!)

best regards
Markus
