SUMMARY

The discussion focuses on the functionality of pasting images in the Post Composer of the PF platform, specifically utilizing the Froala WYSIWYG editor. Users can paste images directly from their desktop or other web pages, which triggers JavaScript to capture clipboard data and dynamically create an IMG element. Additionally, the process includes sending the image data to the PF server and generating a thumbnail version. The conversation invites insights from Greg Bernhardt regarding the coding of these functions.

PREREQUISITES
  • Understanding of JavaScript clipboard API
  • Familiarity with HTML IMG elements
  • Knowledge of the Froala WYSIWYG editor
  • Basic concepts of server-side image handling
NEXT STEPS
  • Research JavaScript clipboard API for image handling
  • Explore Froala WYSIWYG editor documentation for image integration
  • Learn about server-side image processing techniques
  • Investigate thumbnail generation methods in web applications
USEFUL FOR

Web developers, particularly those working with content management systems, frontend developers implementing image handling features, and anyone interested in enhancing user experience through image pasting functionality.

TL;DR
How to implement this thing where you can paste an image when composing a post on Physics Forums?
I have pasted the image below after copying it from my desktop. The image becomes visible in the Post Composer as soon as you paste it. It also works if you copy from another web page.

I assume that JavaScript is able to grab the data from the clipboard and create an IMG element on the fly, and also send the IMG data to the PF server. It can also create a thumbnail version.
How to code these functions?

Thread 'Use of AI (ML/DL) in Science'

We have many threads on AI, which are mostly AI/LLM, e.g,. ChatGPT, Claude, etc. It is important to draw a distinction between AI/LLM and AI/ML/DL, where ML - Machine Learning and DL = Deep Learning. AI is a broad technology; the AI/ML/DL is being developed to handle large data sets, and even seemingly disparate datasets to rapidly evaluated the data and determine the quantitative relationships in order to understand what those relationships (about the variaboles) mean.
