Are you set with the cherry blossom image? I see it on your site already, looks like you cropped it:
The other images come from different sources. If you let me know which image you’re interested in – preferably with a link to the specific post it’s on – I can look into whether the image is available freely, and provide a link to its source.
In addition, impossible to put a picture on this site!
Could you explain where you’re trying to add a picture and at what step you’re getting stuck? We’d be glad to help.
