Ah, I found the problem. Looks like it was loading the world file, but the file
had an error in it. Using that CPL_VSIL… parameter helped verify that the file
was being read:
$ gdalinfo --config CPL_VSIL_CURL_ALLOWED_EXTENSIONS ".png"
/vsis3/bucket/prefix/test_pal.png
ERROR 4: CSLLoad2("/vsis3/bucket/prefix/test_pal.pgw") failed: unable to open
file.
ERROR 4: CSLLoad2("/vsis3/bucket/prefix/test_pal.wld") failed: unable to open
file.
Thanks,
Matt

Matt,
I've just tested and this works for me. Can't think of a reason besides a
permission problem with the .pgw/.wld files, or if you've set the
CPL_VSIL_CURL_ALLOWED_EXTENSIONS configuration option to "png"

Using GDAL 2.4.4, I’m attempting to read a PNG file in S3 with this prefix:
/vsis3/bucket/prefix/image.png. Alongside that object are also image.pgw an
image.wld objects (same content). When I run gdalinfo on the /vsis3 path, I’m
not seeing the geolocation information. Am I doing something wrong? Do I need
a new version? Is this a known limitation?
Thanks,
Matt
