Dolphin service menu options for quickly appending images using ImageMagick.
Both menus require ImageMagick's convert utility to be present somewhere in $PATH. Menu with "Save as..." functionality also requires kdialog.
git clone https://github.com/jwty/dolphin-append-images-menu
cd dolphin-append-images-menu
mkdir -p ~/.local/share/kservices5/ServiceMenus/
cp *.desktop ~/.local/share/kservices5/ServiceMenus/
# Or just install one of the menus, they are independend of each other:
cp appendImagesQuick.desktop ~/.local/share/kservices5/ServiceMenus/
Or install from KDE Store (available directly in Dolphin in Settings -> Configure Dolphin... -> Context Menu -> Download New Services...):
This menu option will try to append selected images vertically (top to bottom) and save resulting image in working directory with filename appended-$UNIXTIME.jpg, where $UNIXTIME is replaced with current Unix time. Unix time is used to avoid overwrites when appending multiple times in same working directory in a simple way. If, for some reason, it is impossible to save resulting image in current working directory save to /tmp will be attempted, with filename created in same way.
Submenu with options for appending images vertically (top to bottom) or horizontally (left to right). After selecting orientation a file save dialog will be opened and a path and file name to save resulting image can be selected.
