Is there any downsides to using GIF as format of all images and pictures on website?

If you're not using it for interlacing and transparency the only real upside would be the compressed file size.

There are no downsides to this as long as the graphics look good.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
