Change multiple images in Writer: PicTool

PicTool
Set independently Name, Size, Colors, Cropping, Anchor, Alignment, TextWrap, FrameStyle, protection and printability of (or delete) a single selected image, all images within a selection or all images (if nothing selected). Images can be filtered by name, FrameStyle and skipped by repeated pattern: 1 means "do", 0 or any other number "skip". For example 001 means only process every 3rd image. (Note: For proper skipping you have to reload the document if you manually changed the order of the images). Images can also be resized only down or only up to new Size by using "up/down"-CheckBoxes. For example "down" means only scale down images that are greater than the new Size.
XShift and YShift can be used to shift images by the same amount relative to their "From Left" and "From Top"-Position.
Hint: If you have nothing selected all images will be changed: Also images in Header, Footer, Footnotes and Endnotes. To exclude these use a selection range. A selection range only affects images in the normal text area and ignores images in Header, Footer, Footnotes and Endnotes. So if you want to change all images but these simply select all (ctrl+a).
If you have selected a textframe all images inside will be affected. To affect textframes instead of images select "Change Frames!" checkbox.
You can always see how many images or textframes are selected in the Titlebar and which images or textframes are selected if you click on the "Filter (Image name contains)"-arrow.
Note: PicTool supports images in tables or textframes but not eg. images in textframes in a table in selection range.
