Have you been getting the message about no space for photo's?
I have, so I've been looking for a solution, at first I thought I would have to pay for extra space but luckily nooooo!
I was directed to Carol of Brum's Blog Apples & Pears which was very helpful, she has a post about making space and a few lovely friends have helped me too along the way (Thank you girls)
Here's what to do (if you have the same problem)
Open Picasa (you can just google it, that's what I did and mine instantly came up)
There you will see your albums of your photos,
choose an album by clicking on it
click on any one photo in that album
select 'actions' from above
go down to edit in creative kit
select resize from the left hand side
fill in the boxes 800 x 800 (sometimes the second set of numbers fill in by themselves)
click on save to my album
then on replace
It's worked for me I have just freed up space which was full, from 99.99% to 76%
and I am doing a few albums a day, so no need to delete any photos, just down size them.
(If you want to find out how much space you have left, In Picasa scroll down to the bottom of the page)
I hope this helps you too.
love & hugs
