Texture image issues

Can anyone shed some light on this issue?
http://answers.unity3d.com/questions/36920/my-textures-arent-working

Basically I am loading textures from a file with www and I am getting a white texture with a red question mark which is not the image and is coming from unity somewhere. I don’t know much about 3d modelling and texturing so I may have made mistakes on that side, but I still think there is a scripting issue here as well.

Is there anyone who has successfully loaded images from a local file whose code I could compare?

Posted a reply on your unity answers question (although it posted as google). Duplicating here for completeness:

From the docs at Unity - Scripting API: WWW.texture it says that if there is a problem with the texture it will display the question mark texture. It also specifies that it must be a JPEG or PNG image. So if you’re trying to load BMPs you’ll get that texture. Try a .PNG and see if it works.

My god, I totally started out with jpgs and just ended up on bmps as it was the last one I tried. It must have been my issues with the coordinates that stopped it working the first time. Thankyou
