When I made a monthly cover photo on our old Y site, I made the banner/photo fit the are that was approximately 250 x 820 pixels in size. I never tried putting up a regular un-cropped or un-resized, ?picture, because I didn¡¯t think it would work right. In Groups.io, I make my cover/banner 300 x 900 pixels.
Hi. I recently set up an i.o. group with the aim of transferring my YahooGroup (although due to the storage limitations I'm not sure this will be feasible). When I created the new i.o. group it had a default banner photo across the top of the page. When I changed the photo to one of my own it appeared as a regular photo rather than as a banner. In my YahooGroup if you change the banner photo the new photo is displayed as a banner too. How do you get your photo to appear as a banner in the i.o. group?
