Step 1: Create or Log in to Your Twitter Account
Before posting any picture, you need a Twitter account.
- New users: Visit twitter.com or download the Twitter app from your device's app store. Click "Sign up" and follow the prompts.
- Existing users: Enter your username, email, or phone, and password to log in. You can log in on desktop or mobile.
Always protect your account credentials to keep your profile secure.

Step 2: Navigate to the Home Timeline or Your Profile Page
Once signed in, you’ll land on your Home timeline, where you can see tweets from accounts you follow.
You can post a picture from:
- Home timeline: Usually the most common place to share updates.
- Profile page: Useful if you’re reviewing your existing tweets or want to post directly from your own feed.

Step 3: Click or Tap the "Post" / "Tweet" Button
On desktop, look for the "Tweet" button labeled with a feather icon in the left navigation menu.
On mobile, tap the + or feather icon at the bottom right corner.
This opens the tweet composition box where you can type text and add media.

Step 4: Select the Photo Upload Option
Within the tweet compose window:
- Click (desktop) or Tap (mobile) the camera or image icon below the text field.
- This allows you to browse your device’s gallery or take a photo directly.
On some devices, you'll see options to:
- Attach GIFs
- Record short videos
- Upload multiple images (up to 4 per tweet)

Step 5: Choose a Photo from Your Device or Take a New One
Once you click the upload icon, you can:
- Select a photo from your gallery.
- Take a new photo using your device’s camera in real-time.
Make sure your file is in a format Twitter supports (JPEG, PNG) and under the size limit (currently 5MB per image).
---
Step 6: Add Accompanying Text, Hashtags, or Mentions (Optional)
You can pair your image with text to boost engagement. For example:
- Hashtags: `#NaturePhotography` or `#EventName`.
- Mentions: Tag other users with `@username`.
Keep the text concise and relevant — it should complement the image rather than overshadow it.
---
Step 7: Use Alt Text for Accessibility
Twitter lets you add alt text (alternative text descriptions) for each image. This improves accessibility for visually impaired users.
Steps to add alt text:
- After selecting your image, look for the "Add description" link (desktop), or tap "Add description" (mobile).
- Enter a brief but clear description, such as “Golden retriever playing in a park.”
Alt text tips:
- Keep it under 420 characters
- Be descriptive, yet concise
- Avoid generic terms like "image" or "photo"
---
Step 8: Preview the Tweet with Photo
Before posting:
- Check the thumbnail displayed in the compose box.
- If it looks cropped or low-quality, consider re-uploading or editing.
Previewing ensures your picture appears as intended in users’ feeds.
---
Step 9: Click or Tap "Tweet" to Publish
Once you’re satisfied:
- Click the Tweet button (desktop) or tap it (mobile).
- Your post will be published immediately, and followers can like, retweet, or reply.
---
Step 10: Check Your Timeline to Verify
Go to your profile or home feed to make sure:
- The image renders correctly and is visible.
- Any hashtags or mentions appear as expected.
- There are no typos or formatting issues.

Tips for Optimal Photo Size and Resolution on Twitter
Twitter automatically compresses images, so starting with high-quality files ensures clarity after upload.
| Image Type | Recommended Dimensions | Format |
|---|---|---|
| Single Image | 1200 x 675 pixels | JPEG or PNG |
| Multiple Images | Varies; similar aspect ratio preferred | JPEG or PNG |
| Profile Banner | 1500 x 500 pixels | JPEG or PNG |
Extra tips:
- Avoid overly text-heavy images — text may become unreadable after compression.
- Bright, high-contrast visuals tend to attract more engagement.

Privacy and Content Guidelines to Follow
Twitter has strict policies about what can be posted:
- Respect Copyright: Only share images you own or have permission to use.
- No Sensitive Content without Warning: Use the "Mark media as sensitive" setting if applicable.
- Avoid Sharing Personal IDs: Don’t post private addresses, phone numbers, or identification details.
- Follow Community Standards: Avoid hateful imagery or any content violating Twitter Rules.
Pro tip: If you want more control, set your account to private in Settings & Privacy so only approved followers can see your posts.
