Ive spent alot of time adding different sized images as the image was getting cropped, think I have resolved that by settling for a 1500px wide image which shows perfectly now , This I feel may be too narrow. so when the page loads in safari on a 21.5 Mac the header image briefly shows a narrower image first then changes to a full sized image that fills the header. Its not the world end issue but id like to know why this happens and how to resolve it if possible. Its just a loose end , after so much fiddling Id like to clean up.
Tried to screen shot it but too fast to capture.
The mobile image, is portrait, works fine ( better in source theme but no time to upgrade the whole site right now ) used under 640 wide
The medium image is 1500 x 600px and I did place the same image in Large as well ( probably wrong ) but if I put a bigger image in ie 2000px it crops. ill send you the link via pm if you want it.
