Problem Description
Right now image gen/edit resolution can only be changed by an admin in the admin panel.
Desired Solution you'd like
Would be great if users can configure their own target resolutions when generating an image, up to an upper limit set by the admin.
Alternatives Considered
None really

🟣 #8965 **Enhancement Requests: Guest Mode, Unified Image Upload Resolution, and Improved Password Security, as options. **
This request is also about controlling image-related settings centrally, specifically admin-defined upload resolution. While it concerns uploads rather than generation/editing, it shows prior interest in resolution governance and limiting image sizes by admin policy.

🟣 #14410 issue: for gpt-image-1 "auto" option for resulotion should be available
This issue is directly about image generation resolution options for gpt-image-1. It requests support for an additional resolution setting ('auto'), so it is closely related to configuring generation resolution behavior.

bug🟣 #8535 feat: Permissions for image generation
This feature request discusses restricting image generation access via user groups and admin controls. It is related because the new issue also asks for finer-grained user-level control over image generation settings rather than a single admin-wide setting.

🟣 #6831 Feature Enhancement: Improve Image Generation Access and Usability
This enhancement targets image generation usability and workflow. It is only loosely related, but it discusses moving image generation controls closer to users, which overlaps with the new request for users to control generation parameters themselves.

Could a custom tool be that solution?
@i0ntempest commented on GitHub (May 8, 2026):
If you mean a custom tool server in mcpo or something similar then not really. It wouldn’t provide the detailed and native control I’d like.
Openwebui already has a somewhat good model of global/user level options, what I’m suggesting is adding image gen resolution control to this model (the admin sets a default and a maximum, users can override as long as it below the maximum, maybe in the session parameters panel).
@Classic298 commented on GitHub (May 8, 2026):
I meant a normal workspace tool
Using userValves and calling open webui's internal image endpoints i think you can achieve that
@i0ntempest commented on GitHub (May 8, 2026):
Could be possible, but currently there's no such tool.
Also official integration would still be better.
@Classic298 commented on GitHub (May 8, 2026):
how would an official integration be better here - and yes there is no such tool but you can very easily build yourself
