 sxiv supports the following command-line options:
 
+    -a           Display all given files, do not filter out unsupported files
+                 (shorter startup time for long file list or slow file types)
     -d           Scale all images to 100%, but fit large images into window
     -F           Use size-hints to make the window fixed/floating
     -f           Start in fullscreen mode
