The way to set the slide timing loop in ppt:
Open the PPT that you need to set up first, I make a new PPT directly here. I need a ppt show of the picture, and I'll just insert the picture.
Then find the "animation" tab in the toolbar, and find it on the right "change mode" where "automatically animate after this:" In the box, enter the time of the slide switch, I entered 20 seconds here. Set here is a slide, to all the 20 seconds a show to remember the next "full application" point.
The above is to set the switch time for each slide show, and the last one will be over.
Find the Slide Show tab in the toolbar, find the "Set Slide Show" button below, and a "set Slide Show" menu where you can find the loop show in Show mode and press ESC to terminate at the front. Then press OK. Each slide will be shown on time until you press ESC to stop.
You can try the effect by pressing the slide show at the bottom right, and you can reset the time if you think it's too long.
Finally, we can save it. Here to remind you just start with the 07 version of Friends, save time Remember to save as "97-2003 presentation" This is the general version of all versions, direct storage is 07 version, 03 version is not open OH.
