Powerpoint

Hello Guy,
Thank you for your post, welcome to the forum, to answer your question; and it is one that comes up quite frequently, I have a method which I use which I find quite effective;
Locate the folder with your image;
Open the slide on to which you wish to place your image, using the rectangle tool, or any other drawing shape create a shape (drag to draw) on your slide of the size you wish your image to be, Right click on this shape, then go to the Format AutoShape option and click, Click the dropdown on the Fill Color, and from the options choose Fill Effects, Click the tab for Picture, Click Select Picture and navigate to the folder where you have placed your image, Select the image and click Insert, the image will fill the drawn shape and you can then complete the resize and hide the borders etc etc.
I hope that helped, if so please click the resolved link, best regards Pete
