The error msg keeps saying “not a valid file extension”
But it is an http// url link to imgur and a blurred image of just 5kb
The actual photo is a png which should be ok
So Idk what's the issue.
iPad says ‘Not secure’ on this site....maybe it won’t link cos of some Apple block?
Dang, this is just getting deeper ! haha
Sorry you are going through this.
Ok, so I am on a Mac/Apple too. And with a link, as you pointed out, none of this should matter.
My image was also coming out burry. I decided to not downsize it myself, and just upload the good full size res image to Imgur. Then type the 90/90 thing in the boxes under the URL here when linking. This gives you the best quality image.
The only reason it might not be working is you are copying the wrong link ? Look for "Direct Link" and make triple sure you also remove any preexisting text in the URL box here before pasting.
And if that doesn't work, then try reformatting the image to .jpg then upload that to Imgur and try again. It should not matter, I agree but I am just trying to go over all troubleshooting.
