I am getting Error 2000 'Picture Web addresses must be less than ${VALUE} characters in length' for a photo URL that specified in the , but the same URL works fine for the node.
Detailed Description
The max of character allowed for Item.PictureDetails.PictureURL property is different compare to the value allowed for Item.PictureDetails.GalleryURL property.
You can use same URL address for both GalleryURL and PictureURL in AddItem call family, but keep in mind that while <GalleryURL> address string can be up to1024 characters, the <PictureURL> is limited to the max length to 150 characters.
