The [_ICON](_ICON) statement uses an image handle from [_LOADIMAGE](_LOADIMAGE) for the program header and icon image in the OS.

## Syntax

> [_ICON](_ICON) [mainImageHandle&[, smallImageHandle&]]

## Parameter(s)

* mainImageHandle&  is the [LONG](LONG) handle value of the OS icon and title bar image pre-loaded with [_LOADIMAGE](_LOADIMAGE) when used alone.
* smallImageHandle& is the [LONG](LONG) handle value of a different title bar image pre-loaded with [_LOADIMAGE](_LOADIMAGE) when used.
* No image handle designates use of the default QB64 icon or the embedded icon set by [$EXEICON]($EXEICON).

## Description

* If no image handle is passed, the default QB64 icon will be used (all versions). If the [$EXEICON]($EXEICON) metacommand is used, [_ICON](_ICON) without an image handle uses the embedded icon from the binary (Windows only).
* Beginning with **version 1.000**, the following is considered: 
  * mainImageHandle& creates the image as the icon in the OS and the image in the program header (title bar).
  * smallImageHandle& can be used for a different image in the program header bar.
* The header image will automatically be resized to fit the icon size of 16 X 16 if smaller or larger.
* Once the program's icon is set, the image handle can be discarded with [_FREEIMAGE](_FREEIMAGE).

## Error(s)

* **NOTE: Icon files are not supported with [_LOADIMAGE](_LOADIMAGE) and an error will occur. See Example 2.** 
* Images used can be smaller or larger than 32 X 32 pixels, but image resolution may be affected.
* It is important to free unused or unneeded images with [_FREEIMAGE](_FREEIMAGE) to prevent memory overflow errors.
* In **SCREEN 0** (default text mode) you need to specify 32-bit mode in [_LOADIMAGE](_LOADIMAGE) to load images.

## Example(s)

Loading an image to a 32 bit palette in SCREEN 0 (the default screen mode).

```vb

i& =_LOADIMAGE("RDSWU16.BMP", 32) '<<<<<<< use your image file name here

IF i& < -1 THEN 
  _ICON i&
  _FREEIMAGE i& ' release image handle after setting icon
END IF

```

> *Note:* _ICON images can be freed if the [SCREEN](SCREEN) mode stays the same. Freed image handles can on longer be referenced. 

Function that converts an icon into a temporary bitmap for use in QB64. Function returns the available image count.

```vb

SCREEN _NEWIMAGE(640, 480, 256)
_TITLE "Icon Converter"
icon$ = "daphne.ico"     '<<<<<<<<< change icon file name
bitmap$ = "tempfile.bmp"
indx% = 6  '1 minimum <<<<<<< higher values than count get highest entry image in icon file

IF Icon2BMP(icon$, bitmap$, indx%) THEN
  img& = _LOADIMAGE(bitmap$) '  use 32 as color mode in SCREEN 0
  IF img& < -1 THEN '           check that handle value is good before loading
    _ICON img& '                place image in header
    _PUTIMAGE (300, 250), img& 'place image on screen
    _FREEIMAGE img& '           always free unused handles to save memory
    KILL bitmap$ '              comment out and/or rename to save the bitmaps 
  END IF
END IF
END
