You might want to consider reading some more before you go ahead as this is a perfect project to start learning about tables and how to make them work together.
That beign said, here is a rough sketch of what I would do (I don't think it matters which mySQL version you are using, I'm not
familiar with the 5).
Table submitter
submitID int(11) auto_increment
name
email
Table photo
photoID int auto_increment
filename varchar(255)
size
width
height
submitter int
createdate date
Table Category
categoryID int auto_increment
categoryName
createDate
Table Album
AlbumID int auto_increment
AlbumName
categoryID int
submitter int
createDate
Table photo_album_join
entryID
photoID
albumID
CreateDate
As you can see, I leave it to you to fill in extra fields and determine proper field types. I hope you also see that ie you get the categoryID in table Album by inserting the selected category (categoryID) from the category table.
