既存の画像を GIMP にとりこむ方法はいろいろあります。
The most obvious way to open an existing image is the menu. Use Open Image dialog, allowing you to navigate to the file and click on its name. This method works well if you know the name and location of the file you want to open. Although the Open Image dialog does have a preview pane, it is not convenient (easy) to find an image based on a thumbnail.

GIMP 2.2 introduced a new Open Image dialog that provides several features to help you navigate quickly to a file. Perhaps the most important is the ability to create 「bookmarks」, or Places, for folders that you use often. Your list of bookmarks appears on the left side of the dialog. The ones at the top, such as 「Desktop」, are provided automatically. Use the Add button to add the current directory to the list. Use the Remove button to remove the selected bookmark. Double-click on a bookmark to navigate directly to that directory.
選ばれたディレクトリーの内容がダイアログの中央部に現れます。 その一覧の上部はサブ (下位) ディレクトリーが並び、 ファイルはその後に整列します。 はじめはディレクトリーにあるファイルがすべて並べられますが、 ダイアログの下部にある ファイル形式の選択 メニューでファイル形式を指定すればその種類のファイルだけが並んで出てくるように制限できます。
整列しているファイルのなかから画像ファイルの項目をクリックすると、 ダイアログの右端にプレビュー画と画像の基本的な属性情報が表示されます。 プレビュー画は作成とともにキャッシュに蓄えられて再利用されるため、 操作後の現状と食い違うプレビュー画を表示することもありえます。 こうした食い違いになっていそうなときは、 プレビュー区画で Ctrl キーを押しながらクリックすれば強制的にプレビュー画を更新できます。
初期設定の場合、 「画像を開く」ダイアログには 場所 文字入力欄があります。 これは隠せます。 Ctrl+L で表示を切り替えるのです。 またこのほか左上の紙と鉛筆のアイコン をクリックしても文字記入欄を呼び出せます。

If you select a file name from the list, and click the Select File Type at the bottom of the dialog to manually specify the file type if this is required. More commonly, though, if GIMP fails to open an image file, it is either corrupt or not a supported format. button in the lower right corner or the dialog, it is almost always true that GIMP will automatically determine the file type for you. On rare occasions, mainly if the file type is unusual and the name lacks a meaningful extension, GIMP may fail to correctly identify the file type. Use |
If you select a PDF file to open, GIMP will show an extra dialog with options specific to this file type.
You can select pages by typing one or more page numbers or
ranges, separated by commas. For example, 4-7,9
selects pages 4, 5, 6, 7, and 9 of the document. The default is to
select all of the pages in the document.
If this is set to Images, then GIMP will open each of the selected pages as a separate image. If it is set to Layers, then GIMP will create one image with each of the selected pages in its own layer.
The size of the image created is controlled by the Width, Height, and Resolution settings. A PDF document contains information about its width and height in units of physical length so it is meaningful to set the width or height of the image in pixels or its resolution in pixels per physical unit of length: as you set any of these three parameters, the other two will automatically adjust to match.
Check this box to apply antialiasing to text in the image.
If you select a PostScript file to open, GIMP will show an extra dialog with options specific to this file type.
You can select pages by typing one or more page numbers or
ranges, separated by commas. For example, 4-7,9
selects pages 4, 5, 6, 7, and 9 of the document. The default is to
select all of the pages in the document.
Note: this is only visible if there is more than one page.

Select B/W to have GIMP create the image as a 2-color indexed image, Gray for a grayscale image, or Color for an RGB image (see 「画像の形式」 for a full explanation of these different image modes). If you select Automatic then GIMP will try to determine the most suitable mode from the contents of the file.
If this is checked, GIMP will use the bounding box information in the PostScript file to determine how much of the page to use: effectively, this is equivalent to cropping whitespace from the edges of the image. It is possible for a PostScript file to contain no bounding box information, in which case this option will be ignored.
You can choose to have GIMP apply antialiasing separately for text and for graphics in the imported image. Either Weak or Strong antialiasing may be applied: usually you should select Strong.
