Hello, this is a part from my database structure:

Table: Item
Columns: ItemID, Title, Content, Price

Table: Tag
Columns: TagID, Title

Table: ItemTag
Columns: ItemID, TagID

Table: Image
Columns: ImageID, Path, Size, UploadDate

Table: ItemImage
Columns: ItemID, ImageID

The items can have more than one image so i have a extra table "Image" and map this images to an items. I see now a problem with this structure. Before i can add Images i must enter an item.

My question is now. Is this structure a good way to solve my problem with many images / tags for one item?

Thank you
