BUG: Images upload

Hi,

About the custom field of the image upload field:

Before, when upload 4 photos it creates 4 custom_fields with ID of photo in Media Gallery.

Example: Upload Photo field name: photo_upload – In post appear 4 times photo_upload with ID in front.

Now, when i upload 4 photos appear the custom fied photo_upload with these format in value:

a:5:{i:0;s:5:”10598″;i:1;s:5:”10599″;i:2;s:5:”10600″;i:3;s:5:”10601″;i:4;s:5:”10602″;}

How to retrieve this content? This is “normal”. If you can help, appreciate.

Thank you
