Error while uploading image on imgur via CURL

I am trying to upload an image on imgur by accessing their API through CURL. I tried:

curl -d "image=reddit.png" -d "key=myapikey" http://api.imgur.com/2/upload.json

It raised a famous error:

{"error":{"message":"Image format not supported, or image is corrupt.","request":"\/\/2\/upload.json","method":"post","format":"json","parameters":"image = reddit.png, key = myapikey"}}

I am also facing the same issue while writing a simple bash script

#!/bin/bash 

API_KEY="myapikey"                                                                                                                                            
file="$1"                                                                                                                                      

output=$(curl -d "image=$file" -d "key=$API_KEY" http://api.imgur.com/2/upload.json)                                                           

echo $output

The ouytput is the same error message as above. I tried it with jpg/png both format raised the same error.

So, any idea what am I doing wrong here.

PS: My imnage is not corrupt and I am executing the script/command from the same directory which contains the image.

Solution

Try this:

$ curl -d "[email protected]" ...

See the manpage of curl for details and read the description of the -d --data option.

Edit:

To encode an image, use the base64 utility:

$ base64 reddit.png > reddit.base64.png
