Midjourney Image Upload Failure Troubleshooting: Expired Links, Format Restrictions, and Commands Not Working

When creating images with Midjourney, the most common issues are “can’t upload the image,” “the reference image doesn’t work,” and “nothing happens after pasting the link.” In many cases, the problem isn’t Midjourney itself, but Discord’s upload limits, inaccessible image links, or unsupported formats. Below is a quick checklist of Midjourney image-related errors, ordered from easiest to hardest to diagnose.

First, confirm whether Discord upload limits are preventing Midjourney from using images

When Midjourney receives a “reference image,” it is essentially reading a publicly accessible image link on Discord; if the upload fails in Discord, Midjourney naturally can’t retrieve the image. First, check whether Discord shows “Upload failed,” and whether the file exceeds Discord’s size limit (a common cap for non-Nitro accounts is 8MB).

The fix is straightforward: compress the image to under 8MB, preferably export as JPG or PNG, then drag and upload it again to the same channel. If you often fail on mobile, switching to the Discord desktop client is usually more stable, and it’s also easier to copy the reference image link correctly.

Midjourney reference image not working: most often the link is “not accessible”

Midjourney only recognizes image URLs that are directly accessible: opening the link should display the image immediately, rather than redirecting to a page that requires login. A common pitfall is pasting a cloud-drive share page, a temporary link from a social app, or a permission-restricted album link directly into Midjourney—then it looks like “nothing happens.”

The most reliable method is to post the image in Discord first, then right-click the image and choose “Copy Link,” and paste that link into /imagine. This way, Midjourney reads a Discord CDN link, which typically has the highest success rate.

Format and transparency-channel issues: it looks like the upload succeeded, but Midjourney parses it abnormally

Midjourney works best with common JPG/PNG files, but some PNGs with special encoding, overly large resolutions, or assets with an alpha channel may lead to “weird styling after referencing” or “weights not behaving as expected.” This is especially common with PNGs exported from design software: they look fine to the naked eye but may include extra color profiles or an oversized canvas.

The troubleshooting approach is “simplify first, then ramp up”: save the image as a standard JPG, keep the dimensions within a typical range (e.g., 1024–2048 on the long side), then retry in Midjourney. If you must use a transparent PNG, it’s recommended to tightly crop the canvas locally and remove extra blank space to reduce the chance that Midjourney misidentifies the subject.

The command is correct but nothing happens: check spacing, order, and permissions

When referencing an image in Midjourney, the image link can go before or in the middle of the prompt, but there must be a space between the link and the text; otherwise Discord may treat it as plain text rather than a recognizable link. Another frequent issue is using Midjourney in a private server channel without granting the bot permission to speak/read messages—so it looks like “the command is sent but Midjourney doesn’t reply.”

It’s recommended to verify with the shortest command first: send only “/imagine + image link” without a long prompt, and see whether Midjourney starts the job normally. If it still doesn’t respond, check the channel permissions to ensure the Midjourney Bot has permissions such as “View Channel,” “Send Messages,” “Read Message History,” and “Embed Links,” then try again.

If it still fails: a quick wrap-up by isolating variables

If you suspect a network or client issue, use a “three-step minimization” to pinpoint it: test in a different channel, test on a different device, and test with a smaller JPG. If any one of these works, you can tell whether the problem is channel permissions, client cache, or the image itself.

If Midjourney only has issues in one channel, check Discord channel permissions and slow mode first; if it fails in all channels, then consider Discord service issues or local network blocking. Once you narrow down the variables, you’ll save a lot of time when you return to generating images in Midjourney.
