I allow my users to upload a single image using the file_upload field - works fine. Once uploaded, the image is returned as a 150x150 thumbnail by default. I would prefer to display a larger size... preferably "large" or "full".
On the image_advanced custom field there is an optional parameter 'image_size' => 'thumbnail/large/full' but this parameter is not available on the file_upload custom field?
Is there a way to display a large "uploaded" image rather than the standard thumbnail in my frontend user submission form.
