<p>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"<o:p></o:p></p>

<p class="MsoNormal"><span style="font-size:11.0pt">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?
