Deluge script for inserting url into image field

I want to insert a url in an image field, looking like this test value

record.photo="<a href='https://www.google.com/images/branding/googlelogo/2x/googlelogo_color_92x30dp.png' target='_blank' title='test'>Test</href>";
The value is inserted into the table with the script with this line:

photo="<a href='https://www.google.com/images/branding/googlelogo/2x/googlelogo_color_92x30dp.png' target='_blank' title='test'>Test</href>"
I'm using a custom script for this.

The script itself runs without errors and all values are inserted, except the value for the field 'photo'. This value remains blank.

My question is: in order to insert a value (url) into an image field with the script, how should the script look like?
