Note that the license for this project is even included with the source at https://github.com/TurboPack/PNGComponents/blob/master/Docs/License.txt. Note how that license is exactly as stated in this issue. Note, however, that the GitHub project is linked to the following license https://github.com/TurboPack/PNGComponents/blob/master/license.txt. Also note that the following repository, created from the same original source from Martijn Saly, also maintains the original license file and is not using a GitHub linked license, i.e., it contains the following, https://github.com/UweRaabe/PngComponents/blob/master/Docs/License.txt. This license mess needs to be resolved. I suggest since the original maintainer has not given permission for a new license, that that be used only and GitHub be updated accordingly.

@chris9672 You must to use Vcl.Imaging.pngimage.pas embedded with rad studio instead using pngimage.pas from package.

Just remove folder PngObj from browsing or library.
