email pic attach no-show

I get jpg attachments from a Yahoo group, and I used to be able to open Gallery or QuickPic and view all the photos sent, without even opening the email.

Now, none of the photo attachments make it to the S3. I have to manually go into the email and download the attachment.

I have:
-- done a jpg search in all folders
-- rebooted phone
-- uninstalled / re-installed Verizon email acct
-- examined settings.

I noticed this started happening after I viewed and deleted all the photos in the folder.

Any ideas ?
