Well will you look at that the problem I am experiencing has been around for almost 6 years and it's still not been fixed!
Just like the others in this thread when other cachers message me and add an image the image is pixelated, it's not all the time just 50% maybe, I have got friends to message me with images to test it out and as far as I can tell it is when the image is sent from a mobile device that isn't on WiFi, but I cant 100% sure so more testing would be needed.
This is what I can talking about, I'm guessing from the previous posts I'm not the only one seeing this, any chance of it being fixed?
