Add Images in Instructions
You can include images in your prompts by hosting them online and then embedding them with Markdown.
This guide uses Postimages — a free, no-signup image hosting site.
Step 1 — Upload Your Image
Go to https://postimg.cc/
Click Choose images and select your image file.
Wait for the upload to finish.
Step 2 — Get the Direct Image URL

Step 4 — Add To Your Instruction
Paste your Markdown directly into your instruction. The assistant will see and process the image.
✅ Tips
Use PNG or JPG for best compatibility.
The image URL must be public — if it opens in your browser without login, it will work.
Keep image file sizes under 5MB for faster loading.
