You are right....you have to hold the end of the strap that is a very skinny loop. Hold the two sides of that loop together and push the pointy end of the loop into one side of the opening and pull out the other side. (It goes under the little "bridge" that is across the opening.)Then open the skinny loop enough to feed the thicker loop end through it. Pull tight and you are done. Good luck. :-)
The more the memory, the more photos you can take on one card and the less frequently you have to buy new cards.
Just make sure to frequently transfer your photos to your computer -- just in case, god forbid, you lose the camera.
I have the GLPH130IS. Although the instruction booklet does say that this model can connect via Wi-Fi I have NOT used that method to download pictures. The booklet states the "camera is an approved Wi-Fi product", and "You can wirelessly connect and send images to" then lists smartphone, another camera, computer and printer. The camera came with an interface cable that plugs into the camera and a computer's USB port and that is how I download pictures. The first time I connected my camera to my laptop, it downloaded software from the INCLUDED CD. There after I just plug the laptop and camera together and download additional pictures. I am NOT a camera person but wanted something simple to use as I do volunteer publicity work for our local library> LOVE this simple and easy to use camera and for me takes perfect pictures.
