when it comes to banners, you have to know the size of the banner space to get one that will work for you. my rough estimate is that the banner space for jive is 1200px by 150px. also when placing a banner that you have used before, or from google, do you change the "background repeat" option:that is in the banner design area?
What I did to alleviate the frustrations of banner issues, like the dreaded "gray bar", is i found a site that lets you create free custom banners, and using those parameters from before I can create any kind of banner and it works 100 percent of the time.
the site that i go to is Banner Maker - Make Your Banner Online for Free | Fotor.com , and I choose the custom button under the "banner maker" options on the main page.
hope this helps!
Thanks for the fotor idea, we'll have to look at that in the future.
Basically this all came up because we had the same banner being used in several spaces, and as far as anyone could spot, the settings were identical, yet one was 'strectch to fit' and one was 'repeating'.
It was after playing with the presets that we found what 'preset' you select causes certain HTML code to be left behind when you go pick your own custom image.
It just seemed peculiar and probably unintentional.
However in this instance, we liked the outcome of the stretch to fit, so this was as much of a 'I think there's a bug' as it was 'here's how to get your image of any size to fit the banner fully'.
you know, that has happened to me in the past as well, before going with fotor. i just thought it was a problem with my browser and refreshed and cleared caches and it seemed to fix it
