Question

I am developing a unity app, in which i call webservice for image url and after getting those url, i call one by one url for image downloading and store those images onto disks, and after in some point i read those images from disks and show as texture, but i am getting problem in reading images. It show me Question mark on texture and when i dig more to find out problem i got that i am getting zero of image using http://www.size and text also nil using http://www.text. I am doing following for reading and writing images.
Writing

if(wwwMarker.isDone)
File.WriteAllBytes(Application.persistentDataPath + "/"+ data.markerName + ".jpg", wwwMarker.bytes);

Reading

//fileurl is string which contain path of file 
fileUrl = (Application.persistentDataPath + "/"+ markerDataObject.markerName + ".jpg");
if(System.IO.File.Exists(fileUrl))
if(www.isDone)
video.mIconPlane.renderer.material.mainTexture = imageToLoadPath.texture;

But when i read this code and show render image on texture it show me Question mark image, but when i load images from assets it works perfectly fine. Please help me that where i am doing wrong. I am nee bee in unity so thats why doing silly mistakes. This will be great for me. Thanks in advance.

Note, that unity’s WWW can only dowload and save as textures JPG and PNG images. If you will try to download an image of any other format, you will get a red “?” image as result.
