Image watermark after uploading post image

I realise that gravityfroms will not add a watermark to an image when uploading an image via a "post" form (which will go in as a draft post) but what i wanted to know is if i used a standard plugin to watermark an image would this work with the way gravityforms works or would the watermatking plugin get bypassed?

Also, anybody know of a good watermarking plugin?

Really hope this is possible as gravity forms is perfect in every other way!

Thanks

I've set up a watermark plugin that only works when I upload an image through the Wordpress media uploader on a post, not when I send it through the gravity form onto the custom post type for the photos.

The watermark plugin's documentations had me insert a function in my media.php file of the Wordpress admin (bad practise I know) but that does make me think I could write a code snippet that will trigger the watermark function after submission by gravity forms.

Ideally I would like the uploaded image to be processed by the watermark script and then also by the theme so it could go straight to publication without me handling it.

the watermark plugin function was

// INSERT HERE!!!
	MM_Execute_WM($file,'');

could I get a code snippet that will cause the watermark script to process the file sent by gravity forms? that would make my day.

Sorry but I'm really not a coder and can't quite figure out what that code is doing or how I need to change it to invoke the watermarking function. I'm quite helpless with that..

add_action("gform_after_submission", "set_post_content", 10, 2);
function set_post_content($entry, $form){

    //getting post
    $post = get_post($entry["post_id"]);

    //changing post content
    $post->post_content = "Blender Version:" . $entry[7] . "<br/> <img src='" . $entry[8] . "'> <br/> <br/> " . $entry[13] . " <br/> <img src='" . $entry[5] . "'>";

    //updating post
    wp_update_post($post);
}

I'm thinking that I need to change the part after changing post content. But I'm not sure how to write the code that will get the image file name, and run the function I need.

should it be something like this?

add_action("gform_after_submission", "watermark_post_image", 10, 2);
function watermark_post_image($entry, $form){

//Get post image
$photopost_id = get_post($entry["post_id"]);

// Here's where I get stuck -- what do I write to call the uploaded image for watermarking? 

//Watermark post image
MM_Execute_WM($file,'');

My image field is ID 3 in the form. I am really stuck at this point.. please help me out?

Hi Chris,

Yes, definitely. I've posted an example form here:

http://photography.crowdsourced.travel/gravity-edit/

The instruction for the watermark function is here:
http://www.wp-watermark.com/installation

It asks me to put in the function into the Wordpress media.php file located at /wordpress/wp-admin/includes/media.php.

This makes the watermark work automatically on standard uploaded images via wordpress editor, but images sent via the gravity form do not get uploaded the same way.

I hope that's all the information needed to make this work? Thanks for your help.

Sorry to bump this guys, but am hoping to get support from you on this one as I still need the images to be watermarked upon upload and publication by the gravity form.

Help appreciated..

actually, scratch that, I don't want to actually watermark my original images, I want to watermark the published images, which has to do with the theme I'm using, not gravity forms.
