Attaching images — six per message.
Photos, screenshots and reference images, attached straight to a Compose message. We shrink them for you before they upload — and we refuse SVG, on purpose.
You can attach images to a Compose message — a photo of the job, a screenshot of the competitor post you're reacting to, a reference for the look you want. Six per message, four megabytes each, and we shrink them for you before they're uploaded.
Attaching an image
Hit the paperclip
On the composer's chip rail, next to the brand chip. It opens your file picker. You can select several files at once.
They queue as thumbnails
Each one appears in a strip above the text box with its name and size. The × on a thumbnail removes it before you send.
Send with your prompt
They're attached to that message, and they stay visible in the thread afterwards — click one to open it full size.
Attachments cost nothing. Uploading, storing and re-viewing them are all free.
The limits
| Limit | Value |
|---|---|
| Images per message | 6 |
| Size per image | 4 MB, after our downscale |
| Formats | PNG, JPG/JPEG, WEBP, GIF |
| Documents | Not supported |
The six-image cap is enforced twice — the paperclip disables itself once you have six queued, and the server drops anything beyond six even if a message somehow arrives with more. Select ten files at once and only the first slots that are free get uploaded, with a note telling you why.
We downscale before uploading
A photo straight off a modern phone is often five to ten megabytes — well over the four-megabyte cap. Rather than reject it, ScoutRival resizes it in your browser before it's uploaded:
- Anything under about 600 KB is sent as-is. No point touching it.
- Bigger files are scaled to a maximum of 1,920 pixels on the long side, keeping the aspect ratio, and re-encoded as JPEG.
- A typical 8-megapixel phone photo lands under a megabyte after this — comfortably inside the cap.
- The file extension changes to
.jpg, because it's been re-encoded. That's expected.
So in practice you shouldn't hit the 4 MB limit at all. If you do, the original was enormous — crop it or export it smaller.
SVG is blocked
An SVG isn't really a picture — it's a document, and it can carry a script inside it. Attachments are stored on a publicly readable bucket and served from our origin, so an uploaded SVG containing a script would be a live cross-site-scripting vector against everyone who opened it. We won't store that.
Try one and the upload is refused with an “unsupported type” message. Export it to PNG and attach that instead — it takes ten seconds and there's no downside for a reference image.
No PDFs or documents yet
Images only, for now. PDFs, Word files, spreadsheets, plain text — all rejected. If you want ScoutRival to work from a document, paste the relevant text into the prompt: you have 4,000 characters, which is several pages.
When an upload fails
- “Unsupported type” — it isn't a PNG, JPG, WEBP or GIF. Most often an SVG, a HEIC straight off an iPhone, or a PDF. Export it to PNG or JPG.
- “Image is still too large after resize” — rare, and it means the original was very large indeed. Crop it or export it at a lower resolution.
- “You can attach up to 6 files per message” — remove one, or send the rest in a second message.
- The upload just stalls — the paperclip pulses while it's working. A failed upload shows a red strip above the composer with the reason. Your prompt text is never lost.
