Easy Practical Apps

Picture Imager
Create Picture Copies with Text and Thumbnails

Current Version    1.0.1

Intended Use

The app saves picture copies with smaller size, text, Exif tags and thumbnails. Making cutouts is also possible.

The resolution of the copy corresponds to the DPI scaling of the screen. For desktop screens, this is most often 96 dpi. This resolution is optimal for display in a browser, but only conditionally suitable for printing.

Four-Step Workflow

Until the copy is saved with or without thumbnails, a preview goes through four steps in succession.

(1) Selection of the picture file to be copied
(2) Dimensions setting of the copy (preview)
(3) Contrast improvement
(4) Text and Exif tags addition

Changes made on the preview are interactive displayed directly.

Function Menus

A three-part menu is displayed in each step.

(1) In the upper box is an arrow for opening or closing the middle box.

(2) In the middle box are the preview-related controls.

(3) In the lower box there is a prominent button for going to the next step.

Start Panel

In the start window, either thumbnails of picture files or the selected picture in its original size are alternately displayed on a panel.

Step 1: Selection

Folders can be opened via the first function menu. All picture files included are then listed as thumbnails on the start panel and serve as origin for the next steps, if selected.

The picture files from subfolders will also be opened.

If several hundred thumbnails are to be displayed, the device resources may be exhausted. If not enough memory is available, the number of thumbnails is limited.

[App folder]
By default, a button is activated by which all pictures from a special folder are listed for selection.

[Folder dialog]
Opening any folder is possible by using the standard dialog.

Picture files can also be selected individually directly via the standard dialog or via the file explorer, the latter if the app is registered for corresponding file types.

The selected picture is immediately displayed in its original size on the start panel. Some information will be displayed. The file path can be copied.

A copy of the selected picture can then be passed as a preview to step 2.

For a different selection, the selected picture can be removed from the start panel.

The displayed thumbnails are displayed alternately with the picture selection until the panel is emptied.

Important: Operating the Sliders

The sliders can be activated with a mouse click for fine-tuning with the left arrow key and the right arrow key.

Step 2: Dimensions

First the dimensions of the preview are to be defined. Displayed on this preview is a copy of the original picture that can be scaled independently.

When initially loaded, the dimensions of the preview and the scaling of the original picture are adjusted to have equal dimensions. The preview thus corresponds to the scaled picture.

More presets are available for quick resizing of the preview.

Presets for established ratios can be selected to change the aspect ratio.

Dimensions and scaling can be set manually, too. The relative angle of the picture can be changed by a slider.

If the picture is larger than the planned copy, cutouts can be made.

Dimensions Presets

The default preview size can be changed via a drop-down menu with various presets.

The scaling of the original picture is adjusted and the aspect ratio remains unchanged.

Aspect Ratio Presets

The aspect ratio can be changed in the same menu by selecting a preset.

[4:3 to 16:9]
After the change, the area of the preview is smaller than the scaled picture. Only a partial area of the scaled picture is therefore shown on the preview and a section can be determined as a cutout.

[16:9 to 4:3]
After the change, the area of the preview is larger than the scaled picture. The scaled picture no longer covers the area of the preview, and the preview must therefore be reduced.

Placement of the Scaled Picture on the Preview Area

If the scaled image is larger than the preview area, it can be placed with scroll bars at the left and the bottom of the preview.

Set Scaling of the Original Manually

The preview area must be completely covered by the scaled picture.

If the original is large enough, the scaling can be adjusted accordingly.

Set Dimensions of the Preview Manually

If this is not possible, the preview must be reduced.

This can be done via a preset or manually via sliders for the preview width and the preview height.

Create a Cutout

If the area of the preview is smaller than that of the original, a cutout can be created.

The slider for the scaling can then be dragged to the right. Afterwards a section can be defined as a cutout with scroll bars at the left or bottom edge of the preview.

Change the Angle of the Scaled Original

The lower slider can be used to change the angle of the scaled picture within the preview.

The oblique edges can then be removed by creating a cutout.

Step 3: Contrast

This step is optional. The contrast of the preview can be changed with a slider. Changes are displayed directly.

Step 4: Text

In this step you can enter the caption and the content of Exif tags.

Image Caption

Text can be entered for two fields. The caption is displayed directly while being entered.

With drag & drop the text can then be dragged into the correct position. Using a dropdown menu, the fields can also be centered horizontally and vertically.

A slider can be used to highlight the font with a background.

Exif Tags

Optionally two Exif tags can be written in the copy. The option can be selected in the settings.

[Exif tag: Exif.Image.DateTimeOriginal]
Optionally, the date of the original is adopted. The option can be selected in the settings.

[Exif tag: Exif.Photo.UserComment]
Optionally the image can be provided with keywords for order and search purposes. The maximum length is 80 characters.

File Types

When opening files, the JPEG and PNG file types are supported. In both cases, the copy is saved as a JPEG file. PNG files are usually larger and do not support Exif tags.

Folder Dialog

In the standard dialog, only folders are displayed. Files are not displayed.

Folder names can also be taken from the address field of the standard dialog by mouse click.

App Folder

[PictureImager || In | Out]
For easy file management, the optional use of a folder in the Pictures-folder with two subfolders is provided. The feature is enabled by default.

A button to open picture files without a standard dialog is activated. Thumbnails of the pictures in the In-folder and possible subfolders are displayed directly on the start panel.

The created preview is saved with or without thumbnails directly in the Out-folder.


Settings can be made for the naming of the newly created files and the size of the thumbnails (several possible at the same time).

In addition, there are options provided for using the Exif tags, the app folder and app animations.

The last option concerns internal rounding correction and should only be switched off in exceptional cases.
