Here you can construct a filter consisting of illustrated buttons.
Select the desired image by clicking on Edit.
With Delete, an
image can be removed again; with Edit alternative text, you can enter text that will
be shown instead of the symbol in end devices incapable of showing
images.
By clicking on Add filter expression, the
filter will be defined that will be activated after the image is
clicked upon in the browser.
If Show image in original size is selected, the chosen image
will be displayed at its original size. If that setting is not
selected, the image will be displayed at 16 x 16 pixels for desktop
screens, and 32x32 pixels on mobile devices.
The setting Filter is initially
active has the effect of turning on the filter when the page
is loaded.
