If you are trying to upload puzzle images at LMI forum, please note the following :

You can't upload files with sizes > 100KB at LMI forum.
For large images, there are 2 options

Option 1)
You can upload such largers files at image hosting sites like http://tinypic.com/ and post the link in forum.
After uploading the image in http://tinypic.com you will get "HTML for Websites".
Copy that and paste in your post.

"HTML for Websites" will look like : <a href="http://tinypic.com?ref=1zn20so" target="_blank"><img src="http://i47.tinypic.com/1zn20so.png" border="0" alt="Image and video hosting by TinyPic"></a>

You can also copy and paste "Direct Link for Layouts" which looks like : http://i47.tinypic.com/1zn20so.png

Option 2)
Alternatively, you can send your files to logicmasteradmin@gmail.com and we will do the needful.

Sorry about any inconvenience, but LMI server has fairly limited space.
