Thought I'd document different options on how to upload files inside a thread for anyone interested (3 methods)...Upload file then edit, copy link and add imageJPG, PNG, PDF and BMP uploads...Pick "reply" to a post, then pick "Attachments and other options"Pick the picture you want to upload - gif, jpg, mpg, pdf, png - file size under 1Mb (total) per postComplete the postAt the bottom of the post, where your file is listed (i.e. picture.jpg), right click on it and pick "copy link address"Now pick the modify option to edit your postPick the icon "Insert an Image", the "paste" your linkFinish the post As can be seen above, PDFs don't display (icon only) and BMPs are not an upload option.Linking from google drive methodShare the google drive image (Select "Anybody with link can view")Copy the link (in my case: https://drive.google.com/file/d/0Bz5SiSu4WNEKREZkOTczdk1zLVE/viewReplace the text "file/d" with uc?export=view&id= (in my case)Delete anything after the long alpanumeric name (in my case "/view"In my case this ends up: https://drive.google.com/uc?export=view&id=0Bz5SiSu4WNEKREZkOTczdk1zLVEUploading via a URLURLs will generally display if paste in the "images" option. If however your image isn't a URL, you can change it to one by uploading to somewhere like pinterest. Method:Open pinterest (you might have to start an account - freePick "Create board" and name it (say "forums")In the new "empty" board that appears, pick "Save pin" then pick "your device", then "choose photo"Pick the photo you want, then "open"If it's a file it accepts, it will preview on the left. On the right under "boards" title, pick, however and the word "save" appears. Pick itTo get the URL, pick the picture preview you now see, then pick it again so it opens up in the browserCopy the URL then you can close that windowNow pick "insert an image" in the forum page and paste that URLUp to you which option to use. The first however might be the quickest and easiest.
of course comes at the risk of loosing the image if the hosting website goes away and full bandwidth needed to get the original that is resized
OK, since no one has done a really comprehensive tutorial on this, here it is:
