problem with translation editor plugin


I really did not know where to post my question but I knew that it is about a plugin and a little is related to this group. I use elgg 1.8.8 and install translation editor 1.2.1 plugin on my elgg but there is some bad results after activating this plugin.

After activating this plugin any picture file or group avatar that I upload to my elgg the picture can not be loaded and the browser does not show the picture correctly.

Any one can help me???
