Pictures Won't Align Horizontally

I have been messing with the photo alignment issues with this theme for weeks now. I have tried various methods and workarounds and simply do not understand why photos will only line up in a vertical line down the page. It looks terrible! There is a gallery option for the format, but NONE of the format options seem to work with the Tempera theme for some reason? I have tried NextGen plugin as well and that was a bust, too. I noticed another user had commented that there is no support for this theme and I am coming to the point that I agree. I have left messages on 2 other topics and I have never received a response from you. This is why I do not donate first. As a consumer I want to know what the developer is about. I guess it is time I switch to a new theme since I cannot get any support to have a ‘useable and attractive’ site with the Tempera theme.
