How do I: Take photo on a path with 20% overlap.
I have a path and I want to take photos along the path and set it by overlap (kinda like a map but on a path -90).
Thanks.

Not completely sure about the overlap on a path. It’s going to take photos of the area depending on your altitude. As far as -90 gimbal, just add a gimbal command at either destination component or along the path with a marker. Maybe a bit more info will help.
If wanting to create path similar to a map pattern then there is no way to set overlap. I helped someone a couple weeks ago and created a Normal type path and then copied that to clipboard and rotated it and place it on top of the other to make a Grid pattern. Unfortunately you will need to adjust the path either closer together or farther apart to get what overlap of photos you would want. More difficult but possible. It will take way more photos but only way to alleviate more photos is to place markers to stop capture and each end of path, then start again while heading beck along the next path stretch.
Here is a plan I create in about 5 minutes and with more work you can set it up as you want.

Not possible right now.
Can you take a photo at a waypoint or marker?
Yes you can - just add a start capture component and set the gimbal orientation.
This will work for me.
If I'm understanding what you want to do -- which I take to be to manually create a map plan? -- you need to start by figuring out the size on the ground of your images, which depends on your camera's field of view and your altitude. The Mini series, for example, has a diagonal FOV of 83° and an aspect ratio of 4:3. A little trigonometry shows that the width of the ground images is a bit more than 1.4 times the altitude, and the image height is a little more than the altitude. So, at 200 feet, each image would be a plot at least 280' x 200'.
The amount of overlap when moving forward will depend on the speed and the photo interval. To get a 20% overlap, you need the photos to be 160' feet apart, so calculate your desired speed in feet per second and divide that into 160 to get the photo interval. Overlap between parallel paths will just depend on the distance between the paths, so for 20% overlap, the paths should be about 224' apart.
