ScreenshotUploader

NOTE: This mod will no longer be developed.
Instead take a look at Image Utils

Summary:

Minecraft forge mod that does exactly as it name indicates. Upload screenshots.
You can either upload to imgur or to your own custom server.

This mod has very little impact in gameplay itself. There are no new items, no new blocks.
It will however make sharing screenshots of your awesome creations a lot easier. One press of a key
and boom. Just paste the link in your discord or skype or whatever you use.

Default keys:

• F4 Upload image
• F2 Save and upload image (override has to be enabled to upload)

Features:

• Direct upload to imgur
• Copy link to clipboard (configurable)
• Upload to your own server

Planned features:

• Add custom server support to upload to your own server
• Filters
• Overlays/watermarks

Changing settings

• you can change your settings by going to mods on the main menu or by going to mod options in the in-game menu.

Uploading to a custom server

Once you've gotten to mod settings there will be a "Server settings" button

Client configuration

Link: link to the upload script Post values: add POST data to your request for servers that require some form of authentication. everything before = is considered as the key and everything after as value you can get the key like this in PHP for example: $_POST["key"] and that would return the value NOTE: {image} is required as this will send the image data. However you can choose whatever key you want. NOTE: dont use spaces between ´=´ they will be added.

Example:

image={image} //send post data with image as key and {image} as value
key=2DAC1D297E6E7E348E5CE1884A7FC //send post data with key as key and 2DAC1D297E6E7E348E5CE1884A7FC as value

if you are using some image hosting service make sure to look up what data you need to send. If you use your own upload script you can pretty much do whatever you want.

Server configuration PHP

NOTE: PLEASE for the love of your own sanity, USE VALIDATION or anyone could upload anything to your server. 
This is a VERY basic example. With very little security to keep it fairly simple and straight forward. you can read https://security.stackexchange.com/questions/32852/risks-of-a-php-image-upload-form to find out more about security

Make sure to change the $key dont use the one given here.
