I was writing a document in Google Docs, and tried to insert an image. Strangely enough, it always gave the same error, “Unable to upload image at this time. (5)” I’ve searched for this error, and as a result tried to upload in different file formats. No luck there. So I’ve decided to post a question in their support forum. Unfortunately, they moved the support from Google Groups to their support site, and at first use you should provide a “username” and accept their terms of conditions. But at this stage I get an “Unknown error” from Google. So, no way to find any answer, and no way to ask my question for an answer.
