How to Complete Image Upload Tasks

TL;DR — How to Complete Image Upload Tasks

To get the best results and help the AI grade your work accurately:

  1. Write clearly and darkly on plain white paper (black or blue pen works best).

  2. Take a well-lit, straight-on photo — no shadows or glare.

  3. Crop your image so it includes only what the task asks for — no names, notes, or extra text — and make sure it’s visible, centered, and upright.

  4. Upload it as a .jpg, .png, or .webp file. 

That’s the quick version — scroll down to learn more.

Some Stemble tasks ask you to draw a diagram, label a process, or show your work by uploading an image. These tasks are automatically graded by our AI — so making sure your image is clear and easy to read is key. Here’s how to get the best results.

✏️ Step 1: Draw Your Work

  • Use plain white paper — lined or coloured paper can confuse the AI.
  • Write clearly and darkly (black or blue pen works best).
  • Keep your drawing centred on the page and leave some space around the edges.
  • Make sure labels and text are legible — print instead of cursive if possible.

📷 Step 2: Take a Clear Photo

  • Use your phone camera — no scanners or screenshots needed.
  • Place your paper on a flat, well-lit surface (natural daylight is ideal).
  • Hold your camera directly above the paper, not at an angle.
  • Avoid shadows, glare, and blur — if it looks fuzzy to you, it’ll look fuzzy to the AI too.

✂️ Step 3: Crop and Check Your Image

  • Crop out any extra text, names, or unrelated content. Upload only what’s asked for in the task.
  • Make sure your image is visible, centered, and upright before submitting.
  • Cropping helps the AI focus on exactly what it needs to grade — and nothing else.

💾 Step 4: Upload Your Image

  • Upload one clear photo per question unless the instructions say otherwise.
  • The system accepts .jpg, .jpeg, and .png files.
Having trouble uploading your photo?
  • If you’re using an Apple device, your image might be saved as a .HEIC file, which the AI can’t read yet. You’ll need to convert it before uploading — and remember, renaming the file won’t work.
  • Check out our Troubleshooting: Converting .HEIC or .PDF Files guide for quick, easy steps to fix it.

💡 Pro Tips

  • Double-check your upload before submitting — you can re-upload if it looks blurry or sideways.
  • The AI focuses on clarity, accuracy, and completeness — not artistic skill.
  • If your image gets flagged or graded unexpectedly, reach out to our support team with your course name, assignment name, and task number so we can take a look.
