Here a little script to load a TGA image file and create a GDI+ bitmap. Currently supported TGA formats are 1/8/15/16/24 and 32-bit.
As v0.85 is written completely in AutoIt, it might take some time to convert larger 8/15/16/24/32-bit images. ☕
_GDIPlus_TGAImageLoadFromFile.au3 UDF
v0.85 without assembler acceleration code but with RLE support:

; Name ..........: _GDIPlus_TGAImageLoadFromFile
; Description ...: Loads a TGA compressed (RLE) / uncompressed image file (1/8/15/16/24/32-bit) and converts it to a GDI+ bitmap format.
; Syntax ........: _GDIPlus_TGAImageLoadFromFile($sFile[, $bPrintInfo = False.])
; Parameters ....: $sFile - TGA file name to load from disk.
; $bPrintInfo - [optional] Prints some information about the TGA image to console. Default is False.
; Return values .: Success: GDI+ bitmap handle
; Failure: error 1 - file cannot be opened
; error 2 - TGA image is not in one of these formats: 1/8/15/16/24/32-bit
; error 3 - unsupported TGA image type
; error 4 - unable to read file to struct
; error 5 - unknown TGA pixel depth
; error 6 - return bitmap cannot be created
; Version .......: v0.85 build 2019-11-08 beta
; Author ........: UEZ
; Remarks .......: 8/15/16/24/32-bit images might be slow on converting ^^
