A number of bids have been placed on One Direction self-portraits that are being auctioned for charity.

Every member of the group apart from Louis Tomlinson took to drawing a picture of themselves for volunteer charity vInspire.

The eBay UK auction currently stands at £200 with eight days left to run, so many more bids are expected to fly in.

Psychologist Jo Hemmings meanwhile recently analysed the pictures for The Sun, with the boffin revealing about Zayn Malik's image, which can be seen below with the red hair:

"A huge toothy grin and a well-executed, considered image – this is a boy who is at peace with himself and has a clear sense of self. He's even making a peace sign with his fingers. It reveals he's happy in the band, but sees his role as the mediator. Possibly the most serious member, this reveals maturity for a 20-year-old."

She said about Niall Horan's drawing, however, which can be seen above: "This denotes reservation and a lack of self-confidence – he neither feels he really has a right to be listened too or to speak up. He's also didn't sign it, so maybe he's not quite as comfortable in his role as the other band members."

Liam Payne's image meanwhile can be seen below, with the singer sporting a monkey look.
