You can make a list and append the images to the list:
images = []
for row in data:
images.append(row)
Then, in the template file you have to do something like:
{% for image in images %}
<img src="{{image}}"/>
{%endfor%}
Also just a random tip, if you're planning to put your app in production,
you might want to try using it in Linux.
Anyway, hope that helps.

No need for the complete Path just after /static/ is required.
Pass all your images' path to a list or a dictionary. This is what
images=images is for.

img_list = []for row in data:
img_list.append(row[0])
So, pass your images' path into a list or a dictionary.
return render_template('index.html', images=img_list)
You've already done 75 percent of the work. Now the static function needs
to be called to serve the images. This is what your template code will look
like (index.html):
{% for i in images %}<img src="{{ url_for('static', filename=i }}"
/>{% endfor %}
