The flexible screenshot setting let's you decide how often a screenshot for a webpage is captured. You can capture screenshots as often as every minute, or only once every 12 months and everything in between. The most used settings are once a day for webpages that change on a daily basis and once a week for webpages that do not change that often.
When you add a new webpage to Stillio you can specify exactly how the screenshot should be taken. One of the settings is the 'Scheduling' option. You can set the 'frequency' and the 'frequency unit'. When you set the frequency to 1 and the frequency unit to days, a screenshot will be taken once a day. When you set the frequency to 2 and the frequency unit to weeks, a screenshot is taken every 2 weeks.
Setting the screenshot frequency will change the number of screenshots that are captured in a month. When you capture a screenshot once a day, this will result in about 30 screenshots a month. Setting the frequency to once an hour generates around 720 screenshots a month.
