Hi angiesvoice,
As Ed mentioned, I also suspect you are only seeing the saved listings you have created over the last month on your Saved Listings page because the "Listings from last ____ days" drop down menu in the upper right section of the page is set to "30".
However, I would like to add that we also provide the option to delete saved listings along with the associated images on our the new version of the Saved Listings page, which you can reach by clicking the “Try out our new and improved Saved Listings page!" on the default Saved Listings page, in case that helps you delete your old images more efficiently.
If you select one or more listings on the new Saved Listings page and click the “Delete” button, you should be given the option to “Delete Associated Images” along with the saved listings you have chosen to delete.
I hope this helps. If you need any further assistance with your account, please feel free to contact us by mousing over the “Help” tab and selecting the “File Support Case” option and we will be happy to continue working with you.
