Views doesn't split content into seprates list items
Assuming all of these images are in a multi-value field:


Make sure your view is showing "Fields" instead of "Teaser" or some other display setting
Add your multi-value image field through the Fields section "Add" button
Configure the field by clicking on it. You should see a pop-up window with collapsible sections at the bottom - the top section is "Multiple Field Settings". Open that section. Turn on the setting "Display all values in the same row"; when you click that, it'll open the "Display Type" options, for which you'll pick either "Ordered list" or "Unordered list" (assuming unordered list, since you use  in the question's code).
