Step 1: Google images >Â light blue >Â got me an image that was 1920 x 1200.
This was saved and after saving it the size became less than 500 x 500.
Step 2: I opened the image with Microsoft Picture Manager and selected custom size. I chose 2560 for the length because Youtube requires 2560 x 1440. When I changed the width to 1440, and saved the newly resized image it shrank back to 2311 x 1440. I tried again and got the same result.
Step 3: Created a Youtube Channel to experiment and added channel art and got the 2311 x 1440 light blue image on the webpage. (see image)
I located the other image shown below and saved it to my system and went back to Youtube to try to add it to my light blue background. Copy is an option when right click on the image but paste is not an option when cursor is put on the Youtube wall paper.
The image showing the cross is less than 500 x 500.
What is being done wrong?
