images and image field problem

[yaniv_form]

Hi

I would like the user to be able to upload an image that will be scaled proportionally to the size of the field pre determined.

I understand that options of image field: "scale image proportionally" is meant for this exactly.

For some reason, this works with images but not with image fields.

please see a printscreen I have made of the problem: same field size and same image uploaded

thanks
