That size restriction makes giving photographic evidence of problems difficult. For example on DPR people were always wondering why there was some problem with the IQ they were getting. They would then upload a photo to show what they were talking about. Very often those problems could be seen only when blown up to a large size. I suppose a crop showing the problem could be used. When you say embed an image do you mean there will then be no size restriction?I changed that now to 2048x2048 pixels and 500KB. And we will se how this will go.
We have to figure out in the nexts couple of months, what the best compromise would be.
But you can of course also embed your images. Se the FAQ and click on the link in my signature.
