@hcrouche , if Design Tools is enabled in your school's account and in your course, you should see a Multi Tool LTI link in the left hand navigation of the course. If it's not there, check Settings for the course and enable the navigation link on the course menu. In addition, the Content Editor Tools are accessible through a rocket that appears at the upper right of the page; when you hover on the rocket, you'll see a slide-out that reads "Launch Design Tools." Last, the Upload/Crop/Embed Image LTI tool is in the RCE tool bar.
If you're not seeing any of what I've just described, I recommend that you check with your Canvas Admins to get an update on the status of their Design Tools installation. And my responses all refer to CIDI Labs' product; if I've misunderstood your question entirely, please post back with additional details.
