Use the existing browser interface to watermark only the local photos I specify.

Tool: https://watermark.noxxxx.com/batch-watermark-photos/?lang=en
Approved input files: [paste the exact local file list]
Expected input count: [number]
Watermark text: [your exact credit line]
Output destination: [an approved new destination, or the browser's normal Downloads folder]

Settings:
- One text layer; use the exact text above, Arial, weight 600, white.
- Size: 4% of the short edge. Opacity: 0.7. Position: Bottom right. Margin: 4%.
- Shadow on; outline, auto contrast and tiled watermark off.
- No crop, rotation, flip, border or frame. No per-photo overrides.
- JPEG, encoding quality 0.92, long edge 1200, metadata Remove all.
- Filename prefix agent-, suffix -watermarked, no additional output sizes.
These are requested settings for this job, not universal best settings.

Process:
1. Check that you can operate a browser, choose the approved local files and receive downloads. Do not assume your browser runs on my computer. If it is remote or would require transferring the photos elsewhere, explain that and wait for my choice.
2. If files, count or watermark text are missing, ask only for the missing information. Use a fresh empty tool session. Wait until the controls are ready.
3. Choose Add photos and import exactly the listed files using the supported file chooser. Do not search unrelated folders. If you cannot use the chooser, ask me to select these files, then resume. If fewer files import, report the discrepancy instead of silently continuing with a smaller job.
4. Apply and read back the requested settings. Check the visible labels; do not reuse stale coordinates or silently substitute another feature. Remove unintended extra layers or old settings in this fresh task. Do not apply a recipe over an unrelated session.
5. Review each preview. If the credit is unreadable or covers an important detail, identify the image and ask for a placement decision; do not change the agreed settings silently. Do not claim automatic subject detection. For a larger job, first run a small approved pilot.
6. Choose Download ZIP once. Wait for the tool's completed/failed result. A click alone is not success. If a download appears after a slow response, do not click again just to obtain another copy.
7. If your tools permit, verify the downloaded ZIP exists, opens, contains one JPEG per input and has the expected dimensions without upscaling. Check a downloaded image visually. If archive inspection is unavailable, report that the export was received but contents remain unverified. Ask me to inspect them rather than inventing verification.
8. Keep sources and existing output files intact. Save a new copy; do not overwrite. Do not upload photos to another service, publish posts, create accounts, change permissions or install software for this task.

Report:
- Status: verified / exported but unverified / partial / blocked.
- Imported inputs, generated outputs, failed outputs, and cancellation status, using observed values; mark anything unknown as unknown.
- Actual output location, dimensions checked, and the file visually reviewed.
- Any manual step or unresolved issue. Do not claim all files succeeded when the tool reports failures or when the archive has not been checked.
