I received a quick reply from Houzz about using Photobucket: "Because you can upload 4 photos at a time directly to your post, embedding photos from other sites is not supported. You can always add a link to your photos on photobucket, however they will not be displayed as images in the forums."

The camera icon labeled Photo no longer works for me (for at least a month) (Opera browser). But I have luck using the house icon labed Houzz Photo. First I place a copy of my edited photo on the outer area of the desktop. I keep my browser window smaller than my screen so I can drag the photo into the dotted square. Sometimes it takes 20 sec. + to appear. Heavy traffic? After it appears click on insert button. Houzz reduces the pictures to 500 pixels width. Mine are usually wider and the program Houzz uses to resize them is very good. You can click on a photo in a post and it will open to its pre-Houzz-resizing. Better able to see detail. So I'd rather use a slightly larger size.

Sometimes I have problems posting pictures also. The app is slow uploading. Pictures that appear to be sideways somehow fix themselves after I have finished editing. I have double pictures in idea books that I have to delete. Crazy but like they say patience is a virtue.
