Photos

Doesn't seem to  make much difference when edited and downloaded from PC photo files.

Trial. Resized using Paint on laptop to 500pix to see if line disappears. It was still the same so removed the photo.The 1 on the 22/10/18 was resized using the photos program loaded on the laptop which only gave the options of S, M or L.

Test

I saved this from my website to my desktop (PC) and it saved at 362 kbs and had no trouble loading. In the past we had to actually resize the picture to certain dimensions which we no longer have to do.

My I pad is still saying Please ensure all files are under 500kb. when  I try to give you a photo without putting it through the re-sizer. No change here. 

And when I re size it comes straight through - a photo of a very casual campsite which we liked. Camping les Chalottes.

If you look at the page script, the grid size for a photo is 468 pix wide. Why have a system that places grey strips either side of a photo, then places an obscuring grey bar across the bottom of the photo? Try resizing by width rather then file size. 

Brue, this is your photo at 300 pixels wide. Will there be a grey band?

element {

visibility: visible;
width: 100%;
left: 0px;
bottom: 0px;
transform-origin: left bottom 0px;
transform: scale(1) translate3d(0px, 0px, 0px);
opacity: 1;

it's the "Bottom: 0 pix that causes the grey band across all uploaded photos regardless of size or width! I can delete the line in firefox and the grey band vanishes!

Nope for me it’s still saying files need to be under 500kb
