Is this when you are authoring a HTML form in Formscentral or when you are trying to collect data in Formscentral. Attachments are not support for PDF forms. If you post the URL to your form we can have a look and see if we can assist you further.
Not sure how to post the URL? I'm inserting an image on FormCentral but when I save as a PDF, it does not appear.
I'll take over while Andrew is out right now.
Is it an image you are uploading from your computer or are you adding from Google or Flickr?
If it is an image you have uploaded - can you send the image to me at email@example.com and I will take a look?
Alternatively if you are adding it from the web can you either share your form with me firstname.lastname@example.org following these instructions (and include the subject of this forum post in the invitation): http://forums.adobe.com/docs/DOC-2462
I'd be happy to look into this further.
I recieved the image and it turns out the image uses CMYK color profile which is not supported in the PDF FormsCentral generates. We'll look into handling this case but for now users can change the color profile in an image, here is an article on color profiles from Adobe which describes how to do this using various Adobe tools: http://help.adobe.com/en_US/creativesuite/cs/using/WSBB0A8512-8151-408c-9F79-4A9E9E3BA84C. html
I have fixed/modified this particular image so it will work in PDF.
