title: Drupal images issue after enabling cache
body: <p>As much as 75% of images are not loading on my Drupal 7 website.  The images in the public folder are being overwritten/renamed with number extensions (Original was: myimage.jpg but is replaced with myimage_0.jpg or myimage_1.jpg, etc).  This breaks the image links.  Both the original image and the styled version have this same issue.</p>
  
  <p>When editing the node or the view, all the images are visible.   But after saving, the majority of images are not visible and link to a non-existent renamed image file.</p>
  
  <p>I thought it might be permissions-related.  The images folders are 755.  Maybe cache-based problem? Although the problem is not corrected when flushing all cache. I do not have imagecache but do have all performance cache enabled, then installed Boost to increase site performance due to slow loading time.</p>
  
  <p>Is there a way to prevent Drupal from continually renaming/overwriting the original image files or other solution?</p>
