I will try to guide to the way of attaching images:
( sorry if this looks too childish
- On the bottom-right side of this message, click on the button named "Reply" (not "Quick Reply")
- Write your post
- Below the writing zone there are 2 buttons, the first to attach an image (1280x1024 max or 300 KB max. Try it to be a png or jpg instead or bmp), and the second to attach a file (zip, txt,... or 120 KB max). If you're using a monitor with a resolution of ~1900 don't copy the full screen, cut only to the daily view window.
When you have your image, open it with the button for images, select the file, and then click at the right, where it says "img" between square brackets.
Unless I can see what's your problem I couldn't help you.
