HOWTO attach an image (i.e a digital signature) to a document and display it as soon as user uploads the image

[jpuser]

Just documenting this in case it will helps someone else…

I’m using this for digital signature on purchase orders (not electronic signature as in electronic records, electronic signatures - but just a “digitized signature”). Anyway here we go…

1. Create an “Attach Image” field…

2. Create "an “Image” field below it…

3. edit the “Image” field and add

read only
Options: [name of “attach image” field] (in my case image_upload1)
Fetch From: [name of “attach image” field] (in my case image_upload1)

Looks like this…

Now I create a new record for the doctype (my test doctype is “truck”)…

First / creating record entry, there will be no signatures/signers yet…

now I go back into the record again (i.e. as a purchaser order signer/approver would during an approval workflow)…

I click attach…

As soon as I upload my image, it is displayed…

Save record and done.
