Ok, sorry for the late reply - I hope this helps!
The 'URL' that it asks for means that it wants to know where on the internet the picture is saved.... Most of the time family photos are stored on your computer - so to get them on the internet - I would recommend one of many free services (but the easiest I find) out there as Turkkm has said - use photobucket.com
It is SUPER easy to set up an account on photo bucket - click on the register button and it will ask you for basic information. From there the instructions are pretty clear - Once the photo has been added - on the very left hand side you click on the text i've highlighted on the image - come back to the LDL page and paste in the text

If anyone needs this further explained I will just write it up starting from the ground up nooo problem!
It's an explanation, but I understand everyone has varying levels of knowledge and this may not be intuitive for some users - so don't be afraid to speak up - if there's issues I'll make a ground up walkthrough
