When adding images manually to an image gallery as content, after adding the 2nd picture, I get an option to define height and width. If I define them, the info is added to the image name, e.g., scan0001-v2.jpg?500x400
If i save the gallery like this, only the first two images are visible in the gallery.
scan0001-v2.jpg?500x400 (not visible)
What is the purpose of defining width and height here?
I assumed it would serve as a kind of resizing, defining the maximum images size.
What I would like to achieve is to batch resize all my images. They all vary slightly in size, which generates a slight offset in the images raster preview. Moreover, I would like to limit the size of an images when in full view.
Do I have to resize them manually before uploading them, if I want to use the image gallery?
