OK, I just found a workaround using PNGs, fair enough.

Here we go, just make sure to call _GDIPlus_Startup() before calling this function:

Func GUICtrlCreatePicEx($sFileName, $iLeft, $iTop, $iWidth, $iHeight, $iStyle = -1, $iExStyle = -1)
    Local Const $STM_SETIMAGE = 0x0172

    Local $hImage = _GDIPlus_ImageLoadFromFile($sFileName)
    If (@error) Then Return 0

    Local $hBitmap = _GDIPlus_BitmapCreateHBITMAPFromBitmap($hImage)
    If (@error) Then
        _GDIPlus_ImageDispose($hImage)
        Return 0
    EndIf

    _GDIPlus_ImageDispose($hImage)

    Local $iCtrlId = GUICtrlCreatePic("", $iLeft, $iTop, $iWidth, $iHeight, $iStyle, $iExStyle)

    Local $hPreviousBitmap = GUICtrlSendMsg($iCtrlId, $STM_SETIMAGE, $IMAGE_BITMAP, $hBitmap)
    If ($hPreviousBitmap <> 0) Then _WinAPI_DeleteObject($hPreviousBitmap)
    _WinAPI_DeleteObject($hBitmap)

    Return $iCtrlId
EndFunc
