title: I cannot get a png image into an image view in android studio
body: <p>I am trying to display a png image in android studio. When I put it into the image view, it will display in the design view but when I try to run the app it gives me the two following errors.
  Error: Invalid file name: must contain only lowercase letters and digits ([a-z0-9_.])
  Execution failed for task ':app:mergeDebugRescources'.</p>
  
  <p>Now I know this means it cannot have upper case letters in the file name but there has got to be a way around this right? My file name is the following:
  C:\Users\Derek\AndroidStudioProjects\CheckItOut\app\src\main\res\drawable\logo2.PNG</p>
  
  <p>I think the error is the fact that the PNG is in all caps, I don't know why it does this. Any help would be greatly appreciated, in case you couldn't tell; I am very knew to this stuff.</p>
