First, edit your form, and add an input to contain annotations datas. So for instance, if you have an image in your form :
{{{field|Main_Picture|uploadable|size=25|image preview}}}
Then change it to add the annotation input :
{{{field|Main_Picture|uploadable|image preview}}}
{{{field|Main_Picture_annotation|input type=editableImage|target=Main_Picture}}}
It's important to set the target param, using the name of the image attribute. Note that you must put it close to your image attribut, and use the 'image preview' param.
Then, in your templafe, to show the image with his annotations, use the following parser function :
{{#annotatedImage:[[File:{{{Main_Picture}}}|frameless|border]]|{{{Main_Picture_annotation}}}}}
