Thoughts on agent-first image hosting, product updates, and engineering deep dives.
GitHub README images not loading? Host them so they never break
Private-repo attachment URLs carry a token that expires in minutes, flipping a repo private→public kills every embed, and the attachment CDN rate-limits. Here's why GitHub images break — and how to host them on a permanent URL you own.
How to host an image with your coding agent
You're mid-session in Claude Code or Codex and an image needs to become a URL. Here's the exact prompt to hand the agent, why the raw API call keeps tripping agents up, and the open-source skill that turns hosting into one command.
imgbox is down? How to rescue your images before they're gone
imgbox is throwing 503s and timeouts, and users are asking if it's dead. The honest truth about rescuing a dying host — and how to save your images while there's still a window.
Imgur images not loading in WordPress? Fix them in one click
Imgur images in your posts turned into blank boxes — from the UK block, deletions, or hotlink limits. Here's a free WordPress plugin that fixes them instantly, and can copy them into storage you own so they never break again.
Hosting images in emails sent with Resend
Resend sends the email but doesn't host your images — and base64 data: URIs get stripped by Gmail and Outlook. Here's the reliable pattern: a permanent CDN URL, one API call, zero egress. Plus why email is the worst-case workload for metered hosting.
Generate images with Nano Banana, host them on PixelVault
Turn a prompt into a permanent CDN URL your coding agent can embed: generate a hero or OG card with Nano Banana (Google's Gemini image model), host it on PixelVault, done. Includes the open-source skill that does it.
Images into remote & cloud coding agents
Your agent runs in the cloud or over SSH and can't take a pasted screenshot. SSH clipboard bridges like cc-clip solve half of it — here's an honest comparison, and why a hosted URL works everywhere a tunnel doesn't.
Fix UK-blocked Imgur images
Imgur was blocked in the UK and hotlinked images went blank. Here's a two-line fix that gets them back — and a way to actually own them so they never break again.
Paste-and-host, for your app
GitHub lets you paste an image into a comment and get a hosted URL. We rebuilt that flow as a drop-in you can add to any textarea — here's why and how it works.
MCP image hosting
PixelVault runs a remote MCP server — connect Claude, Cursor, or any agent and host images as a native tool call.
Image hosting API vs raw S3 + CloudFront
The DIY stack means buckets, IAM, a distribution, and a metered egress bill. An honest comparison — and when each one wins.
Why I built PixelVault
I couldn't get a company invoice for my image host, or serve images from my own domain. So I built the one I wanted.
How to host AI-generated images
DALL·E, GPT Image, Midjourney, and Flux give you URLs that expire in an hour. Here's how to make them permanent in one call.
Host Playwright & CI screenshots on a real CDN
Stop digging through zipped artifacts. Turn every test-failure screenshot into a clickable URL you can paste into a PR.
Image hosting for AI agents
Why agents get stuck hosting images, what "agent-first" really means, and how to wire it up.
