title: Android: Images not visible in gallery after download
body: <p>I wonder if anyone can please shed some light on the following problem.</p>
  
  <p>I am downloading images from a web site to a specific folder on my mobile Android device (HTC Desire HD). The images download perfectly (I see this using ES Explorer). They are not corrupt as I can view the images.</p>
  
  <p>When my app uses a Gallery control to view the images, the Gallery is blank !!!</p>
  
  <p>After playing around for some time I found that if I unmount the SD card and then remount it the images are displayed in the Gallery control.</p>
  
  <p>Does anyone know why this is happening and if so is there a workaround?</p>
