Can anyone offer to help me download a picture + it keeps getting denied ?
What do you mean, from where?
If you use Firefox, press the three dots on the right of your address bar, select "Take a Screenshot", click the image you want to download (if it doesn't recognize as an image, draw a border around it) and then click the download button.
Only certain file types and pixel layouts are acceptable. You should be getting an error message as to your issue
