I upload a new collection of SVG pictures for Valentine's Day in 2012. Pictures for the previous years can be found on the following pages

"You can use them as background pictures or postcards. You can edit it with Inkscape. Every modified picture will be unique.
Unfortunately, SVG pictures (saved with Inkscape) are not displayed correctly by KDE in some cases, so it is recommended to convert them to PNG."

Happy Valentine's Day
