Installation:

To install this component in Delphi's IDE, you'll need to install 2 packages - first the runtime package (Img32_Library.dpk), and then the designtime package (Img32_VCL_Dsgn.dpk). Both these packages are located in Image32's source/package folder. It's important to install the runtime package first. Also, these packages only need to be installed if you want to install TImage32Panel into Delphi'd IDE. Neither package needs to be installed to use the Image32 library.

From Delphi's IDE menu, select File | Open Project and select the Img32_Library package. Compile and close. Then open the Img32_VCL_Dsgn package, compile and then also install.
