一个图片浏览和展示的工具，通过 AutoHotkey (AHK) 的 GUI 功能结合 ImageList 操作，实现图片的动态加载、展示和切换。它使用了 AHK 的 ImageList 扩展库（IL_EX.ahk）以处理图片的加载和绘制。

; H - Integer variable that receives the height, in pixels, of each image.
; Return values: Returns nonzero if successful, or zero otherwise.
; MSDN: http://msdn.microsoft.com/en-us/library/bb761550(v=vs.85).aspx

; Return values: Returns nonzero if successful, or zero otherwise.
; MSDN: http://msdn.microsoft.com/en-us/library/bb761564(VS.85).aspx
; Remarks: When an image is removed, the indexes of the remaining images are adjusted so that the image indexes
; always range from zero to one less than the number of images in the image list. For example, if you
; remove the image at index 0, then image 1 becomes image 0, image 2 becomes image 1, and so on.

; IL_EX_Replace(ILID, Index, HBITMAP[, HMASK := 0])
; Function: Replaces an image in an image list with a new image.
; Parameters: HBITMAP - A handle to the bitmap that contains the image.
; HMASK - A handle to the bitmap that contains the mask. If no mask is used with the image list,
; this parameter is ignored.
; Default: 0 (no mask)
; Return values: Returns nonzero if successful, or zero otherwise.
; MSDN: http://msdn.microsoft.com/en-us/library/bb775213(v=vs.85).aspx
; Ramarks: The function copies the bitmap to an internal data structure. Be sure to use the DeleteObject()
; function to delete HBITMAP and HMASK after the function returns.

; IL_EX_ReplaceIcon(ILID, Index, HICON)
; Function: Replaces an image with an icon or cursor.
; Parameters: HICON - The handle to the icon or cursor that contains the bitmap and mask for the new image.
; Return values: Returns nonzero if successful, or zero otherwise.
; MSDN: http://msdn.microsoft.com/en-us/library/bb775215(v=vs.85).aspx
; Ramarks: Because the system does not save HICON, you can destroy it after the function returns.

; ======================================================================================================================
; IL_EX_SetBkColor(ILID[, BkColor := 0xFFFFFF])
; Function: Sets the background color for an image list.
; Parameters: BkColor - The background color to set as RGB integer.
; This parameter can be the CLR_NONE (0xFFFFFFFF) value; in that case, images are drawn
; transparently using the mask.
; Default: 0xFFFFFF (white)
; Return values: Returns the previous background color if successful, or CLR_NONE (0xFFFFFFFF) otherwise.
; MSDN: http://msdn.microsoft.com/en-us/library/bb775217(VS.85).aspx
; Remarks: This function only works if you add an icon or use ImageList_AddMasked with a black and white bitmap.
; Without a mask, the entire image is drawn; hence the background color is not visible.
; ======================================================================================================================
IL_EX_SetBkColor(ILID, BkColor := 0xFFFFFF) {
If (BkColor <> 0xFFFFFF) && (BkColor <> 0xFFFFFFFF) && (BkColor <> 0xFF000000)

; ======================================================================================================================
; IL_EX_SetImageCount(ILID, NewCount)
; Function: Resizes an existing image list.
; Parameters: NewCount - A value specifying the new size of the image list.
; Return values: Returns nonzero if successful, or zero otherwise.
; MSDN: http://msdn.microsoft.com/en-us/library/bb775226(v=vs.85).aspx
; Remarks: If an application expands an image list with this function, it must add new images by using the
; IL_EX_Replace() function. If your application does not add valid images at the new indexes, draw
; operations that use the new indexes will be unpredictable.
; If you decrease the size of an image list by using this function, the truncated images are freed.
; ======================================================================================================================
IL_EX_SetImageCount(ILID, NewCount) {
Return DllCall("ComCtl32.dll\ImageList_SetImageCount", "Ptr", ILID, "UInt", NewCount, "UInt")

; IL_EX_SetSize(ILID, W, H)
; Function: Sets the dimensions of images in an image list and removes all images from the list.
; Parameters: W - The width, in pixels, of all images in the image list.
; H - The height, in pixels, of all images in the image list.
; Return values: Returns nonzero if successful, or zero otherwise.
; MSDN: http://msdn.microsoft.com/en-us/library/bb775224(VS.85).aspx
; Remarks: All images in an image list have the same dimensions.
; ======================================================================================================================
