On 18 July 2007, Miller had been linked with a move to Preston North End. On 13 August 2007, West Bromwich Albion manager Tony Mowbray confirmed that he was interested in taking Miller on a season-long loan. On 15 August Miller completed a season long loan to West Brom with a view to a permanent transfer. "Ishmael will give us a different option up front," Mowbray predicted. "He's a big, quick, powerful lad who is looking for an opportunity to play more regularly. He will increase competition for places with the other strikers we've already got at the club." He scored on his debut for West Bromwich Albion with an individual effort in their 2–0 home win against Preston North End on 18 August. He had been on the pitch for only seven minutes, having replaced Kevin Phillips, the other scorer in the game, in the 66th minute. He scored on his first start for Albion against Ipswich Town and helped the team to a 4–0 victory, before scoring twice in Albion's 4–2 home loss to Cardiff City. Miller's form during October led to his nomination for Championship player of the month, but the award went to Stoke City's on-loan defender Ryan Shawcross. He was further recognised later in November, when he received his first call-up to the England under-21s.
